PART 1 - GENERAL The FD6000 Series flowmeter is designed to General measure the flow of liquids and slurries in full-pipe closed systems. The transmitter is field configured to measure flow on a variety of pipes and liquids. The standard product is typically used on pipe sizes ranging from 1 - 120 inch [ 25 - 1524 mm ] pipe I.D. - Page 7 PART 1 - GENERAL The flowmeter is typically used as a unidirectional Measuring Limits meter and is most accurate when the transducer is mounted in the orientation detailed in this manual. But, the meter will measure flow in both directions — although flow direction will not be indicated or totalized properly.

PART 2 - TRANSDUCER INSTALLATION The following list outlines how to install the Transducer Mounting transducer for optimal performance, highest reliability Locations and greatest accuracy: 1. Select a transducer site at least 10 pipe diameters downstream from bends, or fittings and 5 pipe diameters upstream. - Page 12 PART 2 - TRANSDUCER INSTALLATION operating range of the meter. Down stream from pump or orifices, etc., locate at least 20 diameters. See Table 2.1 Transducer Cable 2. On horizontal pipe, select a position that is between 2 and 4 o’clock on the pipe, with 12 o’clock representing the top.

- Page 21 PART 3 - TRANSMITTER INSTALLATION PART 2 - SERVICE AND MAINTENANCE The 4-20mA output is proportional to the flow rate 4-20mA OUTPUT measuring scale and can drive a load of up to 1000 ohms. The output is isolated from earth ground and circuit low. Connect the load to the 4-20 mA connection terminals located on the inside of the enclosure, matching polarity as indicated.

The transducer cable carries low level signals. Do not attempt to add additional cable to the factory supplied transducer cable. If additional cable is required contact OMEGA Engineering to order a transducer with the appropriate length of cable Cables to 300 feet [90 meters] are available. - Page 23 Verify that DT6 transducer connections are proper and secure. If the SIGNAL STR. remains greater than 000100, consult OMEGA Engineering assistance. It is possible that the GAIN control [R13] is set too far clockwise and ambient noise is influencing the readings.
- Page 24 PART 3 - KEYPAD CONFIGURATION After a successful flow meter installation and startup (covered in the previous sections of this manual) the FD6000 can be keypad configured to provide select engineering unit readings of flow and a scaled 4-20mA output. Configuration inputs are made via the keypad and are stored by the microprocessor.

All configuration constants will be lost and the FD6000 will load default values for all constants. I.D. Allows entry of a pipes internal diameter. Internal diameters must be entered if volumetric flow rates are to be displayed.

- Page 29 PART 3 - KEYPAD CONFIGURATION The External Counter output, available at the two terminals labeled CTR on the Main PCB, is influenced by the TOTAL MULT value. Since the output is designed to operate electromechanical accumulators, large flow rates will require that the TOTAL MULT be set to a value usable by these types of counters (typically speeds no faster than 3 cps).

PART 3 - KEYPAD CONFIGURATION (continued) Third press Restarts the internal totalizer/external CTR (The internal totalizer starts from zero.) If inhibiting (pausing) the totalizer is necessary, there are two methods suggested: 1. Connect and external totalizer to the CTR terminals.

Typically, a liquid flowing at a velocity greater than 0.2 FPS [0.06 MPS], with adequate suspended solids (100 ppm or 100 micron or larger solids) or aeration, will produce SIGNAL STR readings of at least 000125 counts.
- Page 33 PART 3 - KEYPAD CONFIGURATION FUNCT} 4 mA The 4-20mA output on standard FD6000 Series flow meters is scaled at zero flow equals 4mA and 20 FPS (6.08 MPS) equals 20mA. The 4mA key allows fine adjustments to be made to the “zero” of the 4-20mA output or allows offset to be placed on the 4-20mA output.
- Page 34 PART 3 - KEYPAD CONFIGURATION FUNCT} 20mA The 4-20mA output on standard FD6000 flow meters is scaled at zero flow equals 4mA and 20 FPS (6.08 MPS) equals 20mA. The 20mA key allows fine adjustments to be made to the “span” of the 4-20mA output. To adjust the 20mA output, an ammeter or reliable reference connection to the 4-20mA output must be present.
