The water flow sensor is a device used to sense the water flow rate in a tank. There is a Hall element in the flow sensor. When liquid flows by the sensor, it drives the Hall element inside the sensor to rotate. By calculating the rotate speed of the element, the water flow sensor can give a prcise outcome of the water flow rate passed by the pipe.

  • Inlet & Outlet Diameter G3/4''
