The FP7002 Series Paddlewheel Flow sensor/transmitter flow system provides a low cost, factory calibrated, simple, and easy to install solution for applications requiring a remote long distance flow and temperature sensor located away from the main indicating meter or controlinstrumentation. When ordered with an FP7000 series installation fitting, the sensor/transmitter is factory calibrated to match the flow rate of the fitting selected. Example: if you ordered an FP7002 sensor/transmitter with an FP7010 PVC fitting, the analog output of the transmitter will be factory calibrated to give 20 mA output at the max flow rate of 50 GPM and 4 mA out at 0 GPM. The analog output can be converted to 1 to 5 Vdc output in the field without recalibrating the system. Also now included into the FP7002 design at no extra charge is an independent temperature sensor/transmitter with an industry standard 2-wire, 4 to 20 mA loop output scaled over a 0 to 100°C temperature range.

Paddlewheel Output
Accuracy: ±2% FS
Repeatability: ±1% FS
Power: 12 to 18 Vdc @ 50 mA max
Output: 3-wire, 4 to 20 mA (1 to 5 Vdc with external 250 &trodeks; resistor)
Max Loop Resistance: &trodeks = (Vsupply–12 V)/0.02 A
Wetted Materials:
   Sensor Body: Polypropylene
   O-Ring: FKM
   Paddle: PVDF
   Locking Nut:
      FP7002: PVC
      FP7002A: Brass
Fluid Temperature/Pressure Range: Do not exceed maximum ratings of the piping. Depending on the material of the fitting, the operating temperature/pressure may be limited by the piping and not by the sensor. For all PVC tee fittings, do not exceed 150 psig @ 27°C (80°F), 100 psig @ 38°C (100°F), 60 psig @ 49°C (120°F) or 30 psig @ 60°C (140°F), owing to the insert in the tee. FP7000 sensor: 0 to 26°C (32 to 80°F) up to 150 psig; max pressure decreases 1.1 psig per each 0.56°C (1°F) above 27°C (80°F) for a max temperature of 93°C (200°F) at 18 psig max
