Short Description :   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.
