  2. 2. PFT Flow TransmitterInsertion Paddlewheel Transmitter A square wave output signal is generated with frequency proportional to flow velocity
  3. 3. FeaturesBearings and shaft offerexcellent wear protectioneven in applications withparticulate for long lifeWeatherproof andsubmersible rated forirrigation applications
  4. 4. FeaturesThe PFT uses inductive sensing to sense theblades of the impeller as they rotate. Sensortechnology does not use magnets allowing lowflow rate monitoring and no concerns withmagnetic material in the flowPaddlewheel, shaft and bearings are easilyfield replaceable
