Page 7: System Description
1 System Description The DeltaFlow 180 is an EPA compliant Pitot tube based flow monitoring system. The three main components of the system are the instrument panel, probe, and sample line. This section describes in detail each of these components. 1.1 Instrument Panel The Instrument panel is typically mounted in a climate controlled area, and can be provided with or without an enclosure. - Page 8 The controller has two external modules, the analog module and the form C relay module. The analog module is used to take in 4-20mA signals from the various sensors on the instrument panel, and transmit analog signals out of the instrument panel, such as velocity and temperature. The form C relay module is used to relay status signals, such as fault or sample valid.

Page 9: Differential Pressure (Dp) Transmitter
1.1.2 Differential Pressure (DP) Transmitter This device converts the pneumatic differential pressure signal measured by the probe to a 4-20mA signal. It also provides a gauge style display to aid in troubleshooting the electrical signal. The gauge needle can be zeroed and the 4-20mA signal can be calibrated at the display. Various ranges are available;... -
Page 10: Absolute Pressure Transmitter
Fig. 1-4 Solenoid Valve Manifold 1.1.5 Absolute Pressure Transmitter Absolute stack pressure is needed to calculated velocity and standard volumetric flow. The DP transmitter cannot continually measure stack pressure on its own. For this reason, the Deltaflow comes standard with a 0-30 psia (61.1 inHg, 1551 mmHg) pressure transmitter. The transmitter is plumbed to the static pressure line, and wired to input 3 of the analog module. -
Page 11: Precision Differential Pressure Switch
Fig. 1-6 Stack Temperature Transmitter 1.1.7 Precision Differential Pressure Switch In order to provide a repeatable upscale differential pressure for daily calibration checks, a precision DP switch is tied into the high side of the DP transmitter plumbing. During the beginning of a span check this DP switch will shut off SV6 when it senses the correct pressure has been achieved on the high side of the DP transmitter. -
Page 12: Sample Filters
1.1.8 Sample Filters The differential pressure transmitter used in the Deltaflow is meant to only come in contact with clean non- corrosive air. The Deltaflow purges the sample lines at a minimum of every 6 hours to ensure they stay filled with clean instrument air. As added protection, each side of the DP transmitter has sample filters that contain 13X molecular sieve, soda lime, and indicating Drierite®. -
Page 13: Probe
1.2 Probe The Deltaflow Pitot tube probe assembly consists of an S type Pitot tube, a K type thermocouple, and a 4” mounting flange. All wetted components are constructed of Stainless steel. The Pitot tube comes in various lengths, and the insertion depth is adjustable for easy installation. Once the desired insertion depth is determined the Pitot tube is secured in place using a large compression fitting. -
Page 14: Theory Of Operation
2 Theory of Operation The DeltaFlow 180 is a Pitot tube based gas flow and temperature monitoring system. Like all Pitot tube flow measurements, the Deltaflow uses equations derived from the Bernoulli Principle. The Bernoulli Principle states that for certain flow conditions the total energy of a streamline is constant between two points even if pressure, velocity or elevation changes. - Page 15 Where: = stack gas velocity, m/sec (ft/sec). = Type S pitot tube coefficient, dimensionless, Default 0.84. ΔP = Velocity head measured by the Pitot tube, Pa (in. H = Stack temperature, °C (°F). = Absolute stack pressure, mm Hg (in. Hg) = Molecular weight of stack gas, wet basis, g/g-mole (lb/lb-mole).

Page 16: Installation
The Deltaflow installation checklist contains a number of questions that must be answered by the user before assembly and calibration of the system may begin at the Teledyne Monitor Labs factory. This is provided at the time of purchase or it can be downloaded off the Teledyne Monitor Labs website. -
Page 17: Environmental Conditions At Instrument Panel Location
Configure menu, see section 4.3. If the Deltaflow shipped configured for DHCP the Teledyne Support Tool software will need to be used to detect the DeltaFlow and what IP address it has been assigned on the network. This can be downloaded from http://www.teledyne-ml.com/downloads.asp... - Page 18 Click the Configure Device link to start the configuration process. A dialog box with all detected devices will be displayed. Using the check box, select the device you want to configure and click OK. Page 18 January, 2018...

Once configured, enter the IP address/delta/ (example: 172.16.254.1/delta/) into the address bar of any web browser the web interface. 4.1 Data The Data screen will be the first screen displayed once connected. This section will outline all the data screens and their functionality. -

If a parameter is invalid it will also cause any dependent calculated parameters to be invalid. For example invalid Stack Temperature will cause Velocity and Volumetric Flow to be invalid. A YELLOW border means the parameter is in the process of a QA check such as a calibration or interference check. 4.1.2 Data: Alarms This screen keeps a log of the 99 most recent alarms that have occurred. -

fully configured the parameter can be displayed on the main Data screen, configured as an analog or Modbus output, or used to generate a value alarm. Once the input is configured, the Data: Modbus Map screen will display the address of the user defined parameter, see section 4.1.4. 4.3.2.2 Configuration: Inputs: Modbus This screen enables the user to configure floating Modbus inputs to the controller that can then be displayed on the main Data screen or configured as analog outputs. -

like Microsoft Excel. Then by applying a linear or polynomial trend line, a correction curve is obtained. The coefficients from the correction curve can be entered into fields A0 through A5 to obtain a Velocity with very good relative accuracy. See Operation section for more detail. From the factory, Velocity is always the same as Raw Velocity. -

4.3.3.2 Configuration: Outputs: Analog This screen assigns parameters and full scales to the two analog output channels available on the DeltaFlow. Any measured, computed, or user defined analog parameter can be assigned to either channel. See Table 1-1 for all available options. 4.3.4 Configuration: Calibrations These screens are used for detailed configuration of QA checks. -

these two samples are significantly different, the Pitot tubes may have been clogged with dirt or water and the interference check blowback cleared out the clog. 4.3.4.2 Configuration: Calibrations: Evaluations This screen details the pass/fail tolerances, and reference points for the daily QA checks. The span is defined based on the maximum potential flow (MPF). -

4.4 Administrator IMPORTANT: ANY CHANGE TO THE CONFIGURATION MUST BE WRITTEN TO THE CONTROLLER BY GOING TO THE ADMINISTATOR SCREEN AND PRESSING THE WRITE CONFIGURATION TO DF180 BUTTON. This screen displays firmware version, communication status, and enables the user to perform several functions involving sending to or receiving information from the DeltaFlow controller. -
Page 30: Interference Check
5.2 Interference Check An interference check attempts to determine if the data collected is inaccurate due to probe or sample line cloggage. An interference check consists of taking an average DP sample over a length of time defined by the user, performing a blowback, then taking another average DP sample. The pre and post blowback samples should agree to some extent depending on how steady the process is. -

Page 33: Filter Media Replacement Procedure
6.4 Filter Media Replacement Procedure These filters should rarely come in contact with actual stack gas. Since periodic blowback is done every 6 hours at minimum, the sample lines stay filled with instrument air for the most part. Because of this, all the components on the instrument panel should only come in contact with clean dry instrument air 99% of the time. -
