Page 20: Communications Requirements
Introduction Communications Requirements This section describes the requirements for communicating with your B‐Series flow meter. KzComm is a Kurz software application that allows you to access and configure your B‐Series flow meter. Hardware Requirements KzComm uses XMODEM, Modbus RTU, MODBUS TCP/IP, or terminal communications protocols to communicate with Kurz B‐Series devices. B‐Series devices use the XMODEM communication protocol via USB port, or the MODBUS protocol via RS‐485 port or MODBUS TCP/IP. The Kurz USB device driver or FTDI USB device driver must be installed before attempting to connect a computer with a B‐Series device via a USB cable. The B‐Series devices require: A two‐wire shielded cable for Modbus RTU. • For the XMODEM protocol, a USB Type A‐to‐mini B cable. • The Kurz USB device driver or FTDI USB device driver must be installed Note before attempting to connect a computer with a B‐Series device via a USB cable. For the Modbus TCP/IP protocol, an Ethernet cable to a Modbus TCP/IP to RS‐485 gateway. • Software Requirements KzComm is supported on Windows XP, Windows Vista, Windows 7, and Windows 8. All platforms require up‐to‐date service packs. On Windows Vista, downloading the Trend Log has infrequently caused Note the operating system to freeze (no screen activity). Restart the computer as described in your computer hardware manual. Basic computer knowledge is necessary for copying and moving files, navigating file structures and identifying file types, and installing applications. You will need a decompression utility to extract files from compressed file packages. The Kurz USB device driver or FTDI USB device driver must be installed before attempting to ...

Page 24: Mounting & Sensor Placement
Insertion flow meters have a sensor support connected to an electronics head. Remove the protective shipping cover from the tip of the probe support before installing the device. The probe sensors must have direct contact with the process flow. Sensor Window Probe Sensors Probe Support Figure 2‐1. Probe support and sensors Do not bend the probe sensors. The probe sensors get extremely hot when the Important flow meter is powered ON. Do not touch the sensors unless the flow meter is powered OFF and there has been sufficient time for the sensors to cool down. The long sensor is maintained at a specific temperature above the process flow. The short sensor acts as a thermostat to maintain the constant temperature of the long sensor. The insertion flow meter is typically mounted with a compression fitting into a pipe, duct, or on a flange (see Figure 2‐2 and Figure 2‐3). Considerable force can be exerted on the probe support and flange when the process gas is under pressure. Contact Kurz for hardware mounting accessories available for your installation. Duct or pipe reinforcement may be necessary to prevent cracks and leaks at the sensor port depending on the probe mass and application vibration. The insertion depth depends on the duct size and sensor size. The sensor should be center mounted into the pipe or duct so the sensing element is in the middle where there is the most stable flow profile (minimum thermal gradients when the process gas is cooler or hotter than the ambient). Placing the sensor at the center requires using the meter correction factors to reduce the peak velocity to the true average. Refer to Appendix D, Calibration, for setting the correction factors. The probe support must not be altered or modified for any reason. Important Flow down can not measure below ~ 200 SFPM (1 SMPS) on the low end (zero flow cut off is set high as the heat rise off the sensor is competing with the flow down). Above this velocity point the forced convection takes over. 2–2 Kurz Hardware Reference Guide...

Page 26: Figure 2-4. Probe Sensor Placement (Installation Angle) For Wet Gas
Installation For wet gas applications, the ideal location for the 454FTB‐WGF is at a 45‐degrees up angle up from the bottom (see Figure 2‐4) so that condensed water flows away from the sensor. While the vertical‐up (6 o’clock) position is the ideal location to avoid liquid migration onto the sensor, any corrosive gas constituents (such as SO ) collecting at the bottom of the pipe will corrode the probe. Vertical probe installations also work fine when the flow is up. Vertical down 45‐degrees down Horizontal 45‐degrees up Vertical up Figure 2‐4. Probe sensor placement (installation angle) for wet gas environments All flow meters should be installed away from flow disruptions (such as elbows or branches) to ensure the flow meter provides the best repeatability and accuracy. Based on a single sensor velocity measurement, approximately 30 duct diameters are needed to have the profile within 1% of a long run velocity profile; less length is needed for multipoint arrays. Placing a sensor near a fan inlet can result in extra frequent sensor cleaning to remove dirt buildup. Increased humidity near the fan inlet can increase condensation around the sensor and cause dirt to more‐readily stick to the sensor. Moisture vapor (humidity less than 100%) that is dissolved in the air contributes to the total mass flow measured by the sensor. 2–4 Kurz Hardware Reference Guide...

Page 29: Flow Arrow
Installation Flow Arrow Each flow meter has a flow arrow below the sensor electronics head. The arrow indicates the direction of the process flow, as designated in your order specifications. Flow arrow Figure 2‐6. Flow arrow Electronics Head Orientation The B‐Series meter head has two orientations based on the flow direction. Facing the meter display, the standard flow direction is left to right while the reverse flow direction is right to left. The meter head orientation was selected when the unit was ordered. Rotating the head in the field can damage the sensor wires and cause a loose Important connection, result in water leakage, void the warranty, or create hazardous safety violations. The electronics head on the sensor support must be accessible for wiring. Wiring requirements include electrical and communications (computer) connections. For transmitter‐attached (TA) devices with the display/keypad option, the area must allow • for viewing and accessing the display/keypad. For transmitter‐separate (TS) devices, the area must provide a location for mounting the • transmitter electronics and a connection from the transmitter to the sensor electronics. Display/Keypad Orientation Turn off the power to the unit before reorienting the display/keypad to Important prevent damage and potential explosions ignited from electrical sparks. Within the electronics head, the display/keypad can be mounted in one of four positions to improve viewing and access. It mounts to four standoffs using the screws on the keypad. When rotating the display, use standard electronics handling procedures (a wrist strap) to prevent electrostatic shock/discharge from damaging the flow meter. Kurz Hardware Reference Guide 2–7...
Page 30: Mounting Transmitter-Separate (Ts) Models
Installation Figure 2‐7. Display/keypad rotation (with cover removed) Make sure to fully seat the connectors on the ribbon cable used between the sensor electronics and the display board before carefully screwing down the board (screws provided). There is a pin 1 mark on the ribbon connector that must match the circuit board connector at each end. There is an display contrast control on the back of the display/keypad circuit board. Use a small slotted screwdriver to adjust the best viewing of the screen. It is factory set for equal viewing at C and 60 C. The display turns white when it is too cold, and it turns dark when it is too hot. Mounting Transmitter-Separate (TS) Models When you order a transmitter‐separate (TS) configuration there are two separate enclosures: One enclosure is attached to the probe and sensor • One enclosure contains the sensor electronics • The enclosure attached to the probe and sensor is always metal. The sensor electronics are in either a similar metal enclosure or a fiberglass enclosure. If your sensor electronics are in an metal enclosure, the unit includes either a display/keypad or is blind. Electronics in a fiberglass enclosure include a display/keypad. Figure 2‐8 shows the TS enclosures with covers removed, with the electronics enclosure (with the display/keypad option) and a probe support/sensor enclosure. The electronics enclosure and probe support/sensor enclosure are Note matched using serial numbers. These two enclosures are not interchangeable with other TS enclosures. 2–8 Kurz Hardware Reference Guide...
Page 31: Figure 2-8. Ts Electronics With Covers Removed
Installation Probe Support and Sensor Enclosure Sensor Electronics Enclosure (Display/Keypad option) Figure 2‐8. TS electronics with covers removed Using the optional Kurz mounting kit, the TS meter enclosures mount via the pipe nipple, as shown in Figure 2‐9. Two U‐clamps are used around the pipe nipple, which then attach to a metal mounting adaptor frame or pipe stand. Two 0.75” conduit ports for power and signal wires The conduit seal for Ex environments must be directly attached to the enclosure.
Page 32: Field Wiring
Installation Field Wiring It is important to consider the several electrical issues when installing B‐Series flow meters. Review the following relevant sections before installing your Kurz meter: Safety grounding and explosion‐proof enclosure connections • Water protection • AC/DC power requirements and connection • Analog output configuration and wiring of the 4‐20 mA signals • Clip‐on ferrite for all signal wires (if not in shielded conduit) • Discrete alarms • Serial communications • Zero/mid/span daily drift test (EPA 40 CFR part 60 or 75 support) • 5‐wire sensor connection for the TS configuration • Flex wiring connection for sensor connections • Safety Grounding and Explosion Proof Connections To ensure compliance with general safety requirements, all metal enclosures must be grounded to minimize the chance of electrical shock. For explosive atmospheres where a potential ignition source can exist outside an enclosure, properly grounding a metal enclosure minimizes the potential for sparks if a fault current was to occur. Both internal and external grounds are available for Kurz enclosures. Refer to the wiring diagrams in Appendix A, Drawings & Diagrams, for additional information. For hazardous gas areas, wiring going into and out of an explosion‐proof metal enclosure must enter through a conduit seal or cable gland rated for explosion‐proof applications (Class 1, Div. 1 ...
Page 33: Water Protection
Installation The safety labels and ratings for CSA, and ATEX Ex n and Ex d applications, along with the T‐code for both the enclosure ambient environment and the sensor process environment, are provided in the Appendix B, Certifications, Compliance & Labels. The fiberglass TS enclosure has a non‐incendive approval and is rated only for Class , Div, 2 or Zone 2 environments. The TS sensor head is rated is rated for Class , Div. 1 or Zone 1 environments. The electronics board used for the Ex applications is certified as the ‐01, ‐03, and ‐04 for the FD2‐WGF sensors. The configuration is set when the equipment is ordered. If a field replacement of the SC board is required, the board must be compatible with the sensor. Contact your Kurz representative for additional information. Water Protection Water penetration is the leading cause for a malfunctioning flow transmitter. The metal enclosures have a Type 4X, IP66 rating, but water can damage the sensor electronics or wiring terminals if the meter is not properly installed and maintained. To minimize the potential for water damage, use the following protective measures for keeping water out of the flow transmitter components: Install conduit seals near the enclosures on all ports. • Most cable gland designs provide shielded cable termination an environmental seal against • dirt and water. Routing conduit or cable using a water loop and drain near the enclosure ports. • Keep the enclosure lids sealed tight using the supplied o‐rings. • Apply positive pressure dry purge air (a few PSI from a regulator) to the enclosure to keep • condensation out. Kurz meters have a conformal coating on the circuit boards capable of protecting circuitry from condensation that forms from cooling inside the enclosures and conduit. A sensor and wiring leakage test is performed every 10 minutes that sets off an alarm (Modbus, display, NE‐43, and HART) when excessive leakage occurs. ...
Page 34: Ac/Dc Power Requirements & Connections
Installation AC/DC Power Requirements & Connections For both the AC and DC powered versions of the B‐Series, refer to the summarized wiring diagrams in Appendix A, Drawings & Diagrams, for additional information. This information is for both transmitter separate (TS) and transmitter attached (TA) configurations. Examples for 4‐20 mA connections and Modbus are provided with terminal definitions and cable wiring notes. For the metal TS enclosure configuration, the 5‐wire sensor connections must be made as shown in Appendix A, Drawings & Diagrams. The connection between the enclosures must be shielded to maintain the CE EMC rating. For the fiberglass TS enclosure configuration, the 5‐wire connections must be made as shown in Appendix A, Drawings & Diagrams. The connections between the enclosures must be shielded to maintain the CE EMC rating. 24 VDC Powered Flow Transmitters The 24 VDC power is a nominal voltage since all circuits have a regulated supply and will work between / ‐ 10% of 24 VDC. You can also use an unregulated power supply with 50 to 60 Hz ripple as long as the instantaneous voltage is between 21.6 and 26.4 VDC. Surge currents during sensor warm up could require up to 1 A and will fall off after it warms up in approximately 20 seconds. At no‐flow the current will be about 0.2 A and about 0.6 A for high flow rates (20 SMPS). The power is protected against reverse polarity. If there is neither current flow nor output signal, you should check the polarity against the wiring diagram (available in Appendix A, Drawings & Diagrams). The flow transmitter is grounded to its chassis. The 24 VDC power and 4‐20 mA signal have metal oxide varistors (MOVs) to clamp voltage spikes going into the unit. These are 56 V nominal (voltage level at 1 mA) and do not conduct significant current below +/‐ 36 VDC relative to ground. Consequently, the isolated 4‐20 mA signals and alarms cannot have a significant common mode or bias voltage to prevent leakage currents on the MOVs, which can cause an error in the flow measurement if occurring on the 4‐20 mA output. 2–12 Kurz Hardware Reference Guide...
Page 35: Ac Powered Units
Installation AC power connection 24 VDC power connection Green LED - power Figure 2‐10. AC/DC power connection AC Powered Units A universal input 85‐265 VAC and 50‐60 Hz supply generates a nominal 24 VDC to power the device. The AC wiring uses one of the two 3/4‐inch conduit ports for the signal wiring. The AC powered units have a pull tab attached (Figure 2‐11) to the plug to make it easy removing the plug and connecting the AC wiring using a 1/8‐inch screw driver. Discard the pull tab, and use the power wiring to guide the plug in and out of the power supply. Figure 2‐11. AC power pull tab The power wires must be inside the plastic insulator sleeve or wiring label to prevent the wires from catching in the threads of the explosion‐proof lid. The internal ground can be made via the AC power plug or a 10‐32 stud on the circuit board mounting bracket. There is no means of disconnecting power for this unit. You will need a disconnect per your local electrical code. Kurz Hardware Reference Guide 2–13...

Page 41: K-Bar Purge Option
Installation K-BAR Purge Option The K‐BAR purge cleaning is best controlled at the K‐BAR electronics head. The purge function holds the output during the cleaning cycle so the process can be activated automatically. However, it is important to monitor for substantial data change following a cleaning cycle as too much as too much can affect the control system. Increasing the frequency of the cleaning cycles can help avoid substantial data changes. Each K‐BAR with the Purge option (K‐BAR 2000BP) has a purge gas solenoid that is activated from one of the sensor control boards via the Relay 2 output terminal using a 24 VDC, 12 W signal. The common purge initiation contact closure (as shown in Appendix A, Drawings & Diagrams) is fed from the Kurz purge timer, which provides the cycle interval and the K‐BAR sequencing so only one K‐BAR is cleaned at a time. K‐BAR blow‐down tanks can be shared as long as the gas pressure does not drop below the peak flow during cleaning (120 SCFM per sensor); otherwise, each K‐BAR must have its own blow‐down tank. For example, a four‐point K‐BAR has approximately a 500 SCFM peak purge consumption and a 0.4 SCFM bleed flow rate. This requires a 1‐inch pipe size and less than 20 feet between the blow‐down tank and the K‐BAR. Table 2‐2 provides K‐BAR requirements for the Purge option. Table 2‐2. K‐BAR 2000BP Gas Requirements Per Sensor for Purge Cleaning Parameter Requirement Clean air or inert gas Pressure 105 PSIA +/– 30 PSI Purge consumption per sensor 2 SCF per purge @ 1 second valve open time ~120 SCFM flow rate when valve is open Bleed flow rate per sensor 0.1 SCFM The purge timer limits the air supply requirements and frequently permits the sharing of blow‐...

Page 43: Purge Recovery Settings
One purge timer can control multiple K‐BARs. The blow‐down tank recovery time between purge blasts (purge delay) is programmed with S2‐3 and S2‐4, as defined in Table 2‐4. The LED D13 near TB11 turns ON when the timer is waiting to recharge the tank between probe blasts. Adjustment to the recovery time is accomplished via R12, but has a factory default. Table 2‐4. K‐BAR 2000BP Recovery Time Recovery Time (minutes) S2‐3 S2‐4 Open Open Closed Open Closed Closed Purge Interval Settings The interval between the last purge and the next sequence is set by the DIP switch S2 at locations 5 to 8 in a binary code, with each value worth 5 minutes. As shown in Table 2‐5, 1 equals closed, and 0 equals open. Adjustment to the purge interval time is accomplished via R14 on the circuit board but has a factory default. Table 2‐5.

Page 44: Purge Bar Settings
S2‐5 (5) S2‐6 (10) S2‐7 (20) S2‐8 (40) Refer to the B‐Series Operations Guide for information about setting the data hold time during a purge (blast pulse width) and the recovery time between purges. Purge Bar Settings You can set from 0 to 8 K‐BARs per timer cycle. S1 selects the last K‐BAR connected with a one‐to‐ one selection. THe timer will not operate properly if you select more than one switch position; you must select only one switch position. Remote Purge The purge sequence can be remotely started by closing the two contacts at TB11, pins 1 and 2. This is a 24 VDC control signal. If an external start is preferred to the internal interval timer, then the W1 shunt can be installed to disable the internal interval timer. Once the sequence is started, the number of K‐BARs and recovery time are still applicable. Acknowledgement Output Signal An open collector output (24 VDC max, 30 mA max) can be used for signalling a purge operation to the customer equipment (such as PLC). This output is on TB12‐1 and TB12‐2, with ‐1 being the collector and –2 being a ground. Selecting the optional W3 shunt aligns the output with the purge start trigger to the K‐BARs. For example: To set the seconds duration, W3‐1 is jumpered (shunted) to W3‐2, which gives a purge • trigger signal that goes low for each closure on TB12‐1. With a four probe application, there would be an open collector low signal when each probe is cleaned. This pulse is at least 0.5 s but less than 2.0. To set the minutes duration, W3‐2 is jumpered (shunted) to W3‐3, which gives the interval‐ • done or sequence started. The output (TB12‐1) goes low until the last K‐BAR purge trigger is given. With a four K‐BAR application, there would be an open collector low signal that stays low for the entire sequence of cleaning each probe. This could take several minutes depending on the number of bars and recovery time settings. No signal is generated at the purge acknowledgement output (TB12‐1 terminal) when the W3 jumper (shunt) is not installed. 2–22 Kurz Hardware Reference Guide...
Page 45: Analog Output Configuration & Wiring
Loop Powered Wiring The 4‐20 mA linear output is a loop powered isolated signal. The positive output terminal is diode protected against reverse voltage. The principle wiring diagrams for these are shown in Appendix A, Drawings & Diagrams. Self-Powered Wiring The output may be self‐powered in the nonisolated mode by jumpering +24 VDC to one of the two positive 4‐20 mA terminals. Then the 4‐20 mA output is taken from the negative 4‐20 mA terminal to ground. A simplified AO wiring drawing or this mode of operation is shown in Appendix A, Drawings & Diagrams. To use it in the nonisolated mode, the receiving current (PLC or DCS) should be sensed with an isolated input to avoid ground loop currents. AO Capabilities The 4‐20 mA circuit has an 11 VDC compliance at the full 20 mA current. On a 24 VDC 4‐20 mA circuit, at least 11 VDC will be dropped across the 4‐20 mA output, the balance on the load resistor, and wiring. For example, with a 250 ohm load, at 20 mA the voltage drop will be 5 V on the load resistor, 19 V across the 4‐20 mA output or AO terminals. With higher voltage supplies, there is a correspondingly higher load resistance available. As a loop‐powered 4‐20 mA output and a 24 VDC power supply, it can drive 600 ohm and still support the 21 mA NE‐43 alarm. Do not exceed 36 VDC on the loop‐powered interface or there can be leakage current from the protective MOVs causing an error in the measurement. A loop‐powered configuration places a customer provided DC power source, the B‐Series output, and load resistance all in series. NE-43 Alarm Support for the 4‐20 mA signal is provided by clipping normal operation between 3.8 and 20.5 mA. Meter faults are indicated with either a low or high alarm on the 4‐20 mA output. See Chapter 4, Troubleshooting, for more information. HART The HART version of the sensor control board has just one 4‐20 mA or AO. See the Kurz HART Interface Guide for full list of HART commands. The DD for this device is usually all you need as it is self documented. The DD user interface is typically used on a handheld communicator, but is also available for a HART Master running on a computer. Kurz Hardware Reference Guide 2–23...
Page 46: Clip-On Ferrite For Signal Wires
Installation For the K‐BAR multipoint system, the individual sensor electronics boards can interface with a HART handheld computer to monitor the sensor’s dynamic and status information, initiate a zero‐ span check, view diagnostic data, or initiate a purge cleaning cycle. HART should not be used to change an individual sensor’s analog output scale or velocity; these settings must match the Series 155 Mass Flow Computer settings. Clip-on Ferrite for Signal Wires All I/O connections, 24 VDC, Modbus, analog outputs, or analog inputs (4‐20 mA) must be clipped into a ferrite (as shown in the Figure 2‐17 example) to meet EMC specifications. The only exception is if the I/O wiring is in a multi‐conductor braided shield cable with peripheral bonded termination or solid conduit (ridged or EMT). Liquid tight flex does not provide shielding. Note Clip-on ferrite Figure 2‐17. Clip‐on ferrite for I/O wires One ferrite kit ships with each meter. Additional ferrites are available from Kurz and a variety of distributors. Contact your Kurz representative for additional information. Alarms The two optically coupled solid state relays (SSR) can be used for most any flow logic, sensor error output, or totalizer mode pulses. Each SSR is rated for 0.5 A, 24 V AC/DC. As with the other I/O terminals, there are 48 V MOVs for surge protection on this device. Do not exceed 36 V to ground or a leakage will occur. Additionally, the MOV can overheat and become damaged, leading to its failure during a short circuit. See the wiring diagram in Appendix A, Drawings & Diagrams, for the specific alarm terminals. 2–24 Kurz Hardware Reference Guide...
Page 47: Serial Communications
Installation Serial Communications There are two independent serial ports on the B‐Series. Mini‐B USB port • RS‐485 port • After installing the Kurz USB driver, the USB connection can act as a COM port for remote terminal operations. After installing the KzComm application, you can view data, set/upload/ download the meter configuration, and extract diagnostic data from either the USB or Modbus connection. The RS‐485 port can be used for the Modbus protocol and multipoint communications so that you can have access to multiple meters from one location (for example, an office or control room). For additional information about using the USB port and KzComm, refer to “Communications Requirements” in Chapter 1 and the KzComm User Guide. Accessing your flow meter via a USB port requires installing the Kurz or FTDI USB driver on the Windows computer. Both drivers are available on the Kurz customer CD. Once the USB driver is installed, you can use KzComm or a terminal emulator program to access B‐Series information. Kurz recommends Tera Term, which works on all supported Windows platforms (Windows 95 to Windows 8). The serial port settings for the terminal emulator are: Port number ‐ same as the flow meter (the default is 1) • Baud rate ‐ 9600 • Data bits ‐ 8 • Stop bits ‐ 1 • Parity ‐ no • Flow control ‐ no • For additional information about using the USB port, KzComm, and terminal emulators, refer to “Communications Requirements” in Chapter 1 and the KzComm User Guide.

Page 48: Rs-485/Modbus
Installation RS-485/Modbus Computers interface to RS‐485 devices using a USB to RS‐485 adapter. The RS‐485 interface is half‐duplex and supports 9600, 14400, 19200, 38400, and 57600 baud rates. Wiring is a shielded twisted pair (two signal lines and one shield connection). The signal lines can be connected in any order provided the RS‐485 bus is biased so the flow meter can identify the positive signal (refer to Appendix A, Drawings & Diagrams). A junction tee between the network bus and instrument drop is recommended so devices can be removed for service without interrupting the network bus. The USB to RS‐485 adapter is optically isolated, has a screw terminal interface with metal enclosure and status LEDs, and uses a biased bus for auto‐polarity detection. A USB to RS‐485 adapter is available from Kurz. Contact your Kurz representative for additional information. The Modbus interface must be set for the device address, protocol, baud rate, and byte order. Once properly connected and configured, an LED typically flashes when receiving activity and another LED flashes for transmitting or responding to the flow transmitter. B‐Series devices also include two red LEDs, which indicate data transmission between the flow transmitter and the Modbus master by flashing intermittently. The full protocol specification and register variable map is found in Chapter 3, Serial Communications. For K‐BARs using Modbus communication, the following example has 16 sensors that are divided into two independent power and RS‐486 networks. This configuration is designed so a single wiring fault does not disable the whole process measurement. Sensor 1 at flange end. Sensor 4 at probe end. Cable 1 Cable 2 Cables are 24 VDC and RS-485.

Page 50: 5-Wire Sensor Connections
Installation 5-Wire Sensor Connections For the TS version you must field install the wiring between the sensor and its electronics enclosures. Refer to the field wiring diagrams in Appendix A, Drawings & Diagrams, for the TS wiring diagrams. For this 5‐wire connection, use quality wire with a wire resistance less    than 1 per wire. Each wire must be matched within 0.01 (10 m ) for the lead length compensation to work properly and for the factory calibration and temperature compensation to hold in the field. If the individual wires do not meet the matching specification, the length must be trimmed or extended until matches. The terminal strip for the sensor wire will accept up to 12 AWG (2.05 mm) wire size, which is effective for up to 630 feet (192 m) between the sensor and electronics. The electronics terminal block TB1 is rated for up to 14 AWG (1.63 mm) wire size. The 5‐wire connection must have the required shielding to maintain the CE EMC compliance of the product in the TS configuration. This can be done with rigid conduit, EMT, or a braided shielded multi‐conductor cable between the sensor junction box and the sensor electronics enclosures. Sealing the conduit directly to the enclosures is required to meet the explosion‐proof ratings. However, using a peripherally bonded shielded cable gland or simple cable gland‐and‐ shield pigtail ground connection is acceptable. Contact your Kurz representative for hardware accessories information with an Ex d safety rating. Figure 2‐21. Cable gland example with braided shielded cable 2–28 Kurz Hardware Reference Guide...

The three communication methods are: Remote terminal • Data logging • Modbus protocol, ASCII and RTU • Kurz Hardware Reference Guide 3–1...
Page 54: Remote Terminal & Data Logging
Remote Terminal & Data Logging Remote terminal and data logging use the same USB serial port so only one method can be used at time. Communication via the USB connection requires the Kurz or FTDI USB driver to facilitate communication between the flow meter transmitter and a computer. Remote terminal communication is provided through RS‐232 via a standard USB connector • on the sensor control board. Once configured, remote terminal communication allows you to configure a B‐Series flow meter and upload/download configuration files using KzComm or a terminal emulator program. Refer to the KzComm User Guide for parameter settings and configuration information related to KzComm and terminal emulators. Data logging output is in a comma separated value (CSV) format so it can be imported into • a spreadsheet program. Data logging can be setup for periodic time intervals. Terminal echo should be turned OFF to prevent active display data from transmitting with logged data. However, terminal echo must be ON to use the computer keyboard for navigating the flow meter’s onboard menu system. Setting Up Remote Terminal Communications To use the serial interface, connect the flow meter to a computer via a standard USB cable. The cable is a USB type‐A male to USB type mini‐b male. The USB port on the flow meter is accessed by removing the enclosure lid on the backside of the meter, as shown in Figure 3‐1. Once connected, the flow meter must be turned on to establish communication with KzComm or a terminal emulation program before you can access the communications parameters. USB connector Figure 3‐1. B‐Series USB Connector Any terminal emulation program can be used as a remote terminal interface to the B‐Series.

Page 56: Modbus
RS‐485 can be used via the Modbus protocol to communicate with B‐Series devices, but RS‐485 must be configured as half‐duplex in a point‐to‐point or multi‐drop network. When used in a multi‐drop network, each slave device must have a unique device address within the network. The individual slave device address can be assigned in the range of 1 to247. For Modbus serial RTU, the COM port numbers and available COM port options are based on hardware and software configuration. You must use a USB‐to‐RS‐485 converter to communicate via Modbus. A communications port option appears only when there is a physical port or a hardware device is attached to the computer and a device driver identifies it as a COM port. Refer to your converter documentation for COM port identification information. See “Identifying the COM Port” for additional information. Identifying the COM Port If the drop‐down list for the COM Port field does not provide an identifiable name, open Windows Device Manager. You can do this by using one of the following methods: Select Control Panel→Device Manager. • Open the Windows Computer Management window and click Device Manager. • For Windows XP, choose Start→Run, typing devmgmt.msc in the Open field of the Run • dialog box, and press Enter.

As shown in Table 3‐4, Modbus registers are organized into the following reference types identified by the leading number of the reference address: The “x” following the leading character represents a four‐digit address location in memory. • The leading character is generally implied by the function code and omitted from the address specifier for a given function. The leading character also identifies the I/O data type. The on/off state of discrete inputs and outputs is represented by a 1 or 0 value assigned to • an individual bit in the 16‐bit data word. With respect to mapping, the Least Significant Bit (LSB) of the word maps to the lowest numbered coil of a group and coil numbers increase sequentially as you move towards the Most Significant Bit (MSB). Unused bits are set to zero. Table 3‐4. Modbus Register Reference Types Modbus Register Description Reference Address 0xxxx Read/write discrete output or coils. A 0x reference address is used to drive output data to a digital output channel. 1xxxx Read discrete inputs. The on/off state of a 1x reference is controlled by the corresponding digital input. 3xxxx Read input registers. A 3x reference register contains a 16‐bit number received from an external source (for example, an analog signal). 4xxxx Read/write output or holding registers. A 4x register is used to store 16‐bits of numerical data (binary or decimal) or to send data from the CPU to an output channel. Kurz Hardware Reference Guide 3–11...

When viewing variables such as temperature and flow and the data does not appear correct, use another format for interpreting the data registers. Modbus Biasing A B‐Series slave device automatically detects the polarity of its wiring and will correct a polarity error in wiring; however, it requires a biased bus for this functionality to work properly. Refer to the wiring diagrams in Appendix A, Drawings & Diagrams, for additional information.

Modbus Master Device Settings Modbus Master Parameter Value Lead time 184 us Lag time 14 ms maximum If the master lag time is too long, the transmission will collide with the slave response and increase data transmission errors. Response time 18 ms maximum Baud rate 38.4 kbaud Silent interval 35 ms Timeout interval 100 ms Number of retries Framing Remote Terminal Unit (RTU Because of the lead‐lag and response times, the B‐Series is limited to approximately 15 transactions/sec at 38.4 kbaud. For large Kurz Multipoint Systems, this supports a 12‐point duct measurement in less than one second. A common limitation for Modbus devices is that the CPU supports multiple functions and is not always ready to respond to a command from the Modbus master. On a busy Modbus network, Kurz recommends polling a device address multiple times or bypassing an unresponsive address during a device scan. A network scan should not report device errors until a specific number of device requests are unanswered. Kurz Hardware Reference Guide 3–17...

Page 73: Usb Port Ascii Commands
USB Port ASCII Commands ASCII commands allow communicating with the flow meter using a custom software application or a terminal emulator. ESC commands allow you to obtain the process data of the meter. Refer to “B‐Series ASCII Commands” in Chapter 3 for information about issuing ASCII commands. Built-In Diagnostics The flow meter has an extensive set of internal and external sensor and wiring checks it performs and reports. The diagnostic tools provide service technician support and minimize the amount of meter down‐time. Intermittent events are also captured for evaluation and allow for faster corrective action. Some diagnostic tools are designed for the user interface, while other tools are used via Modbus, a terminal emulator, or KzComm. The diagnostic tools are: Event codes with text description appear on the display. • (These also can be echoed to the serial USB port.) Internal event logs containing 200 FIFO records of the event code and meter runtime. • Min/max event memory records 20 daily extremes each for velocity, flow rate, process • temperature, electronics temperature, and the occurrence runtime. Trend data for 20,416 records captured every 10 seconds in volatile memory. This permits • approximately 56 hours of flow rate, temperature, and run‐time data while the meter is powered on. Current event code or meter status read via the Modbus registers, as described in “Internal • Volatile RAM Data Logging ” on page 4‐9. NE‐43 alarm, below 3.6 mA or above 21 mA, which maps many of the errors to NE‐43 • alarms. Advanced diagnostic data accessible through the Display mode menu assists with • troubleshooting by providing numeric data to supplement the event code.

Page 74: Event Code Log
Event Log Error Codes Event Code Description / Causes xxxxxxx1 RP resistance above high limit. The velocity sensor resistance (RP) is above the normal range for the configured sensor type. This accounts for sensor core temperature up to ~650°C before setting the error or ~720°C in 600°C mode. Possible causes: Open circuit on the sensor wiring. Defective sensor or sensor control board. xxxxxxx2 RP resistance below low limit. The velocity sensor resistance (RP) is below the normal range for the sensor type configured. This accounts for sensor core temperature down to ‐112°C before setting the error. Possible causes: Short in the sensor wiring. Defective sensor or sensor control board. xxxxxxx4 RTC resistance above high limit. The process temperature sensor resistance (RTC) is above the normal range for the sensor type configured. This accounts for sensors up to 650°C for the metal sensors, FD, FD2, and MD and up to 460°C on the CD sensor. Possible causes: Open circuit on the sensor wiring. Defective sensor or sensor control board. When the meter reaches the limit, the meter turns off the sensor control drive until it cools. This can cause the sensor to regulate at this temperature and set multiple errors in the log as it goes below and above the limit. xxxxxxx8 RTC resistance below low limit. The process temperature sensor resistance is below the normal range for the sensor type configured. This accounts for sensor down to ‐120°C in normal operation before setting an error. Possible causes: Short circuit on the sensor wiring. Defective sensor or sensor control board. 4–4 Kurz Hardware Reference Guide...
Page 75 Event Code Description / Causes xxxxxx1+ Wire loop resistance above high limit. The sensor wire resistance from the sensor it its electronics board is too high above limit (> 5.0 ohms). Loop resistance is from the electronics out to a sensor and back. Possible causes: Wire is too long for the gage being used. Loose wire joint connection (but not too loose, see code 20). Defective sensor or sensor control board. xxxxxx2+ Sensor RPs lead open circuit. The sensor wire RPs is open circuit or not connected. Possible causes: Open circuit on the RPs wire, pin 1 of TB1. Open on the RP lead will also set this, Pin 3, TB1. Defective sensor or sensor control board. xxxxxx4+ High sensor or wire leakage. The sensor or wiring is showing too much leakage current to ground. The trip point of this error is the equivalent of 100 kOhms leakage resistance. Note: Firmware version newer than 1.09 have a factory configuration option that allows operation up to 600°C for the FD2 sensor. The event code may be preceded by the warning code 2xxxxxxx. Possible causes: Wet or contaminated wiring or junction box. Water in the backend of a sensor. Corroded front side to a sensor. Sensor above temperature limit. Defective sensor control board. At normal temperatures, three 10 minute leakage updates are required before the error is set. xxxxxx8+ Flow rate above design limits. Under high heat flow conditions (very high flow rates), the demand to heat the sensor may exceed the drive limits of the sensor control board. The reported flow readings at this point are compressed and lower than the true flow readings. Note: Applies to 2.x firmware. Kurz Hardware Reference Guide 4–5...
Page 76 Possible causes: This is a normal alarm if the flow rate or temperature is above the kick‐out set point which is user programmable. Condensate on the velocity sensor can cause high heat flow and will set this also. A change in gas composition to high heat flow gases like H2 can cause this alarm. Note: Applies to 1.x firmware. xxxxx2++ Meter kick‐out low. If the flow rate or temperature is below the low kick‐ out limit in the meter. Possible causes: This is a normal alarm if the flow rate or temperature is below the kick‐out set point (user programmable). Drop in process pressure at very low flow rates can cause a loss in heat flow. A change in gas composition to low heat flow gases like Ar or from CH4 to air. Note: Applies to 1.x firmware. xxxxx4++ ADC failed to convert measurement. The circuits on the sensor control board which measures the input signals are not working properly. Possible causes: The sensor control board is defective and needs to be replaced. xxxxx8++ Sensor control drive stopped responding. The sensor drive voltage to heat the velocity sensor is not matching the set point. Possible causes: Short or miss‐wring of the sensor. Defective sensor control board needs replacing. xxxx1+++ Sensor over‐voltage crowbar engaged. The sensor drive voltage was not matching the set point and would not fall to low drive on command. The crowbar SCR was engaged to clamp the sensor drive voltage to zero. Possible causes: Sensor field wiring short to a DC power supply (4‐20 mA) or 24 V supply. Defective sensor control board needs replacing. 4–6 Kurz Hardware Reference Guide...

Page 78 Description / Causes 1+++++++ The subsystem responsible for communicating via the HART protocol is not responding. The unit will not communicate via HART. Note: Applies to HART 2.x firmware. 2+++++++ The sensor is in a process above 100°C and is leaking current. It has 24 hours to recover to a leakage resistance above 100k ohms before the warning is converted to an error. Note: If the leakage resistance is below 20k or the process temperature is below 100°C, it automatically converts to an error. During the warning, the meter continues providing readings. Upon converting to an error, the NE‐43 alarms are set and the meter no longer provides readings. This process allows the sensor to operate while drying out the MI cable. Possible causes: Wet or contaminated wiring or a junction box. Water in the backend of a sensor. Corroded front sided to a sensor. Sensor above temperature limit. Defective sensor control board. Note: Firmware version newer than 1.09 have a factory configuration option that allows operating up to 600°C for the FD2 sensor, and the warning code may be followed by the error xxxxxx4x. Note: Applies to 1.1x and 2.x firmware. 4+++++++ Power on or power cycle. This is a momentary code logged in the Event log for diagnostic purposes. It occurs every time the unit boots up or there is a power cycle. Note: Applies to 2.x firmware. 8+++++++ Configuration change.

Page 138: Raw Velocity
Calibration Raw Velocity Using raw velocity and reference velocity ensures the proper correction factors are loaded into a flow meter for new and recalibrated systems. To set the calibration, you must measure the average flow or velocity using a reference method for each specified flow rate and know the flow rate and correction factor (CF) configured for the device under test (DUT). The correction factor is based on the velocity of the current flow rate, both of which are used for computing the raw indicated velocity: Raw velocity = indicated flow/(area * CF) The output from a multipoint K‐BAR system is generally raw velocity. Single point flow meters require back‐computing the raw velocity data to determine the flow output. The Kurz Modbus Client utility supports flow meter data logging in a comma‐separated value (CSV) format, which can be imported into a spreadsheet application conversion. The flow meter data can then be computed to raw velocity. Using an older Series 155 data logging utility to monitor the DUT during the field Note calibration will require you to temporarily assign a meter to each input channel to record the raw velocity from each sensor. To compute the correction factors for the DUT, enter the reference velocity and indicated raw velocity for each sensor and for each flow rate into the DUT. Any bias or Sensor Blockage Correction Factors (SBCFs) must be accounted for when loading new variable correction factor (VCF) or configuration correction factor (CCF) data. The logged correction factor results from bias * SBCF * VCF. After loading the new VCF/ CCF data, the DUT will read the flow rate as measured by the reference method. Velocity Traverse Data Acquisition The traverse average velocity is acquired using either of the velocity traverse reference methods. The process flow rate must be at equilibrium so the computed average from the traverse reflects the same flow rates on all access points. Developing the insertion depth information requires the following: Noting the center of the velocity probe sensing element, which is 20 mm (0.78 inches) from the • probe end. Determining the start point, which is a variable distance beyond the compression fitting's outside • edge based on conditions that include duct wall thickness and tread adaptors. Locating the probe center at the near wall edge, and marking the probe support with a permanent • marker next to the compression fitting collar.

0.2‐2.3 2‐25 Determined Unusable case‐by‐case data >2.3 >25 Determined Unusable case‐by‐case data Equal Areas for a Rectangular Duct The sample locations for rectangular ducts are determined by simply dividing a cross‐section of the duct into small equal‐area rectangles and then measuring at the center of each rectangle. You can achieve an accurate estimate of the duct's flow profile if there are sufficient access points; at least eight equivalent diameters downstream and at least two equivalent diameters upstream from the nearest flow disturbance such as a bend, expansion or contraction. The recommended access points use 19.05 mm (0.75 inches) compression fittings with a nylon, teflon, or other plastic ferrule that will not permanently adhere to the test probe. Use the following equation to find the equivalent diameter for a rectangular duct based on the minimum sample points specified in Table D‐1: ED = (2HW) ÷ (H + W) where: ED is the equivalent diameter of a rectangular duct. is the height of the duct. is the width of the duct.

Flow Rate 1 Example, 30 Points (75 max. per set) Velocity Insertion Depth (mm) Point 1 Point 2 Point 3 Point 4 Point 5 Compute the average fluid velocity by summing the data and dividing by the number of points. The Series 2440 provides internal data logging and computations. The Series 155 repeats this process for each flow rate, up to four sets, using CCF. Equal Areas for a Circular Duct A circular duct can be divided along the circumference into equal area wedges like slices of a pie and/or along the radius into equal area concentric rings (the lesser diameter of the center ring is considered equal to zero). Wedge Concentric Refer to Table D‐1 for the minimum number of sample points based on duct size and upstream disturbances. The recommended access points use 19.05 mm (0.75 inches) compression fittings with a nylon, teflon, or other plastic ferrule that will not permanently adhere to the test probe.

Page 144: Traverse Probe Blockage
The Series 2440 provides internal data logging and computations. The Series 155 repeats this process for each flow rate, up to four sets, using CCF. Traverse Probe Blockage Small ducts must account for sensor and probe support blockage. The deeper the probe is inserted into the duct blocks more flow and causes an increase in local velocity because of the reduced internal area. When this blockage error is greater than 0.25% you can define a Sensor Blockage Correction Factor (SBCF) to make the observed reading account for the blockage as though it did not exist. Use the following equation to determine if a SBCF is needed:   IDi 0.0025 AD ÷ DP where: IDi is the sensor insertion depth for the specific cell being measured. AD is the inner cross‐sectional area of the duct. DP is the diameter of the probe. Example 3 Using a 19.05 mm (0.75 inches) diameter probe to sampling a circular duct with an inner diameter of 1400 mm (55 inches) requires the following minimum insertion depth to account for blockage:     IDi 0.0025 (1400 mm) ÷ 4 ÷ 19.05 mm = 202 mm D–8 Kurz Hardware Reference Guide...
Page 145 Calibration The SBCF can be defined with the following equation:  SBCFi = 1 ‐ [(IDi DP) ÷ AD] where: SBCFi is the SBCF at the specific insertion depth being measured. is the sensor insertion depth for the specific cell being measured. is the diameter of the probe. is the inner cross‐sectional area of the duct. Example 4 Using a 19.05 mm (0.75 inches) diameter probe to sampling a circular duct with an inner diameter of 1400 mm (55 inches) at a depth of 1363 mm (54 inches) for the 10th sampling point of an access point has the following SBCF:    SBCF = 1 – {(1363 mm 19.05 mm) ÷ [ (1400 mm) ÷ 4]} = 0.9831 The true velocity (VT) is found using the following equation:  VT = VI SBCF where: VT is the true velocity. VI is the indicated velocity. Kurz Hardware Reference Guide D–9...

 is the density of the gas, lb/ft . Additional calculations involve converting the dP units to inches of water and converting the gas density to a function of pressure and temperature. The results are converted to standard velocity instead of actual velocity. The following formula converts gas density to pressure and temperature:  =  (Ts ÷ Ta)(Pa ÷ Ps) where:  is the standard gas density, 0.07387 lb/ft . is the gas molecular weight, MW = 28.96. Ts is 77°F or 25°C in absolute units so 460 + °F or 273.15 + °C. Ta is the actual temperature in absolute units. Pa is the actual pressure in absolute units, in PSIA or Hg. Ps is the standard pressure which is 101.325 kPa, 14.69 PSIA, 760 mmHg or 29.92 in Hg. The following formula converts the differential pressure (dP) from inches H2O into lb/ft :   inches H O ÷ (27.68 in H O ÷ lb ÷ in ) (144 in ) = (144 ÷ 27.68) lb/ft Use the following formula to make the final calculation to convert standard velocity to actual velocity: V = k [dP (144 ÷ 27.68) (2) (32.2) ÷ (MW 0.07387 ÷ 28.96) (Ts ÷ Ta) (Pa ÷ Ps)] (60) Kurz Hardware Reference Guide D–15...

The ambient air pressure is 27.56 Hg. Convert pressure into the same units:  29.92 in Hg + 27.56 in Hg = 28.94 in Hg Pa = (0.68 PSIG ÷ 14.69PSI) Compute the MW of the gas mix:   MW = 0.7 (12 + (4 1)) + (0.3 (12 + (2 16))) = 24.4 D–16 Kurz Hardware Reference Guide...
Page 153 Calibration Compute the standard velocity: Vs = 21745 k [(dP ÷ MW) (Ts ÷ Ta) (Pa ÷ Ps)] SFPM Vs = 21745 (0.84) [0.42 ÷ 24.4 (273.15 + 25) ÷ (273.15 + 37.2)(28.94 ÷ 29.92)] = 2310 SFPM Assuming the measurement was from the center of the 8" duct and the ID = 7.981 results in the following flow rate:     SCFM = SFPM Area CF = 2310 3.1416 (7.981 ÷ 2 ÷ 12) 0.80 = 642 SCFM This would be a large digester flow on a good day. The 0.80 CF is a typical Va/Vp correction factor observed with tracer gas testing on an 8" line. Accounting for the Pitot tube blockage during the measurement results in an area reduction by (0.25 inch x 4") = 1 in . Converting this value to ft with the previous calculations:   SCFM = 2310 [3.1416 (7.981/2/12) ‐ 1 ÷ 144] 0.8 = 629 SCFM Accounting for the test probe blockage is a 2% lower flow rate but slightly more accurate calculation.
