Details for PFT-IDN-B111-S
Insertion paddlewheel flow sensor | pulse output | brass body | 1-1/2" NPT connection | FKM seals | tungsten-carbide shaft | PTFE bearing.
Series PFT Paddlewheel Flow Sensor
The Series 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.
Product Applications
- Irrigation
- Ground water remediation
- Cooling systems
- Pump protection
- Leak detection
- Filtration systems
- Long product life even in applications with particulate due to bearings and shaft that offer excellent wear protection
- Use in irrigation applications with weatherproof and submersible ratings
- Save time and inventory with one unit that is adjustable over a large pipe size range
- Application versatility with a variety of wetted material selections
- Reduce need for additional external components with integral 4-20 mA output
- Eliminate concerns regarding magnetic material in flow due to sensor technology, which uses inductive sensing and no magnets
