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

Features

• 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
