The PFT Insertion Paddlewheel Flowmeters are used to monitor liquid flow rates in pipes from 1-1/2 to 40″ and is available in brass or 316 SS body. The unit outputs a frequency proportional pulsed or 4 to 20 mA output.
The pulse models are a square wave output signal with frequency proportional to the flow velocity and the 4 to 20 mA models have a linear output of the velocity with 4 mA equal to 0 ft/s and 20 mA equal to 25 ft/s.
Output:
- Pulse: NPN open collector with square wave output, rated 60 V @ 50 mA maximum. Frequency: 3.2 to 200 Hz. Pulse Width: 2.5 msec +/- 25%.
- 4 to 20 mA: 4 mA is 0 ft/s, 20 mA is 25 ft/s.
Electrical Connection: 22 AWG shielded UL type PTLC rated 105°C, 20′ (6.1 m) long with cable gland. Can be extended up to 2000′ (609 m) with similar cable. Optional UL listed burial rated cable.
- Process Connections: 1-1/2″ MNPT
- Power Requirements: 10-35 VDC
- Compatibility: Water-Based Fluids
Product Applications : Irrigation; Ground water remediation; Cooling systems; Pump protection; Leak detection; Filtration systems.
