Description
The Series PFT Paddlewheel Flow Sensor is designed to accurately monitor liquid flow rates in pipes ranging from 1-1/2 to 40˝. Available in both brass and 316 SS body options, this sensor offers versatile wetted material choices to suit various applications. It outputs either a frequency proportional pulsed signal or a 4 to 20 mA linear output. With bearings and shafts providing excellent wear protection, the PFT sensor ensures long-term reliability, even in applications with particulate matter. Its weatherproof and submersible design makes it suitable for irrigation applications, while its non-magnetic sensing technology enables low flow rate monitoring without concerns about magnetic material interference.
