Plastic Paddlewheel Flow Meters With Optional RTD Sensor

Fluid flowing through the FPB1400 causes the paddlewheel to spin. As the magnets embedded in the paddle spin past the sensor, electrical pulses are produced in which frequency is proportional to the flow rate. The number of pulses per desired time interval and the K-factor (number of pulses/gallon) make it is easy to calculate the flow rate and volume passing through the unit.
