PART 1 - INTRODUCTION General The FD-400 ultrasonic flow meter is designed to measure volumetric flow of solids-bearing or aerated liquid within closed conduit. Trans- ducers are available as non-contacting (FD-400C) or insertion probe (FD-400I) types. FD-400C non-contacting transducers are strapped to the outside of a pipe and are suitable for most installations where the pipe material supports the transmission of ultrasound.

PART 2 - TRANSDUCER INSTALLATION Unpacking After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately. The transducers that are utilized by the FD-400 contain piezoelectric Mounting crystals for transmitting and receiving ultrasonic sound energy...
Page 11
PART 2 - TRANSDUCER INSTALLATION flow readings will be realized over a very large range of flow. Since products like the FD-400 have software algorithms that assume a full-pipe of liquid, partially-filled pipes can lead to very large flow measurement errors and should be avoided. Select a transducer mounting location with adequate straight runs of pipe, both upstream and downstream, to achieve stable readings Examples of minimum upstream and downstream requirements are...
Page 12
PART 2 - TRANSDUCER INSTALLATION Pipe Preparation Before the transducer heads are mounted to the pipe surface, an area slightly larger than the flat surface of the transducer face must be prepared. If pipe insulation is present, it must be peeled back to expose the pipe surface.
Page 13
PART 2 - TRANSDUCER INSTALLATION Top View of Pipe Figure 2.3 Transducer Placement PROCEDURE: 1. Large pipe installations utilize stainless steel straps to secure the transducers to the outside of the pipe. The FD-400 system is shipped with four 36 inch (900 mm) straps, which are suitable for pipes up to 39 inches (1000 mm) diameter.
Page 14
PART 2 - TRANSDUCER INSTALLATION transducers are to be mounted. Leave the strap loose enough to allow the transducers to be placed underneath. If multiple straps are being used, it can be beneficial to wrap electrical tape around all but one strap connection to secure the strap worm screws in place.
Page 15
PART 2 - TRANSDUCER INSTALLATION FD-400I Probe The FD-400I insertion transducer that is utilized by the FD-400 contains piezoelectric crystals for transmitting and receiving Transducer ® ultrasonic sound energy. The black Ultem plastic tip of the FD-400I Mounting contains these crystals, which are designed to be inserted just into the path of the flowing liquid.

PART 3 - TRANSMITTER INSTALLATION ISO Modules The FD-400 utilizes ISO-MODs for input and output functions. ISO- MODs are epoxy encapsulated electronic input/output modules that are simple to install and replace in the field. See Figure 3.6. All modules are 2,500 V optically isolated from FD-400 power and earth grounds.
Page 30
PART 3 - TRANSMITTER INSTALLATION 4-20 mA Output The 4-20 mA Output Module interfaces with most recording and logging systems by transmitting an analog current signal that is Module proportional to system flow rate. The 4-20 mA ISO-MOD may be configured via jumper selections for either an internally powered (Figure 3.7A) or externally powered (Figure 3.7B) mode.

PART 4 - INSTRUMENT PROGRAMMING Fluid Specific SP GRAV – Fluid Specific Gravity Entry Gravity unitless Allows adjustments to be made to the specific gravity (density) of the liquid. If Pounds (LBS) or Kilograms (KGS) is selected for either the RATE UNT or the TOTL UNT, a specific gravity must be entered for the correct mass flow to be calculated.
Page 39
PART 4 - INSTRUMENT PROGRAMMING System DAMPING – System Damping Damping Relative Percent Entry: 0-99% Flow Filter Damping establishes a maximum adaptive filter value. Under stable flow conditions (flow varies less than 10% of reading), this adaptive filter will increase the number of successive flow readings that are averaged together up to this maximum value.
Page 40
PART 4 - INSTRUMENT PROGRAMMING Configured via jumper selections for either a passive (current sinking) or active (current sourcing) transmission mode (see Part 3 for details), the 4-20 mA Output Module interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system flow rate.
Page 41
PART 4 - INSTRUMENT PROGRAMMING 2. Using the arrow keys, increase the numerical value to increase the current in the loop to 4 mA. Decrease the value to decrease the current in the loop to 4 mA. Typical values range between 40-80 counts.

PART 4 - INSTRUMENT PROGRAMMING collector”. The turbine meter simulation sources a non-ground referenced saw-tooth waveform with a maximum peak amplitude of approximately 500 mV p-p. The open-collector output utilizes a 0.21 Ohm MOSFET output that is rated to operate at 100 V and 1 A maximum.
Page 43
PART 4 - INSTRUMENT PROGRAMMING Two independent SPDT (single-pole, double-throw, Form C) relays are contained in this module. The relay operations are user configured via the keypad to act in either a total pulse output, flow rate alarm or error alarm mode. The relays are rated for 200 VAC maximum and a have current rating of 0.5A resistive load (175 VDC @ 0.25A resistive).

PART 4 - INSTRUMENT PROGRAMMING Configure CFG MOD2 – Configure I/O Module 2 I/O Module 2 The I/O configurations for CFG MOD2 are identical to those detailed in CFG MOD1. Change PASSWORD – Change the Security Password Password 0-9999 By changing the Security Password from 0000 to some other value (any value between 0001-9999), configuration parameters will not be accessible without first entering that value when prompted.
Page 45
PART 4 - INSTRUMENT PROGRAMMING When the unit is powered up, there is a delay before the unit begins transmitting sound into the pipe. During this time, the signal strength is measured and a base signal level is obtained. Typically this is a value of about 20.
Page 46
PART 4 - INSTRUMENT PROGRAMMING Gain Control GAIN POT – Digital Gain Pot 0-64 Using the arrow keys, increase or decrease the numerical value to set the signal gain level. Typically, optimum flow measurement is made when this value is between 10 and 50. Use the lowest value that provides an accurate and stable flow reading.
Page 47
PART 4 - INSTRUMENT PROGRAMMING Linearization LINEAR – Entry of Linearization Data The Linearization feature allows for correction of flow readings caused by non-linear flow measurement. This typically occurs when there is insufficient straight piping before or after the location where the transducers are mounted.

PART 5 - STARTUP AND TROUBLESHOOTING FD-400 Startup NOTE: The FD-400 flow meter system requires a full pipe of flowing liquid before a successful startup evaluation can be Requirements completed. Do not attempt to make adjustments or make Manual configuration changes until a full pipe of flowing liquid is verified. NOTE: If an RTV sealant was utilized to couple the transducers to the pipe, the sealant must fully cure before power is applied to the instrument.
