Introduction:
Water flow sensor is mainly made of a plastic body, the rotor assembly and a Hall flow sensor.Water heater which is mounted on the end, for detecting the water flow, the water passes through the water when the rotor assembly,Magnetic rotor and change as the flow speed, the Hall sensor output corresponding pulse Signal, the feedback to the controller,
the controller determines the size of the water flow, for control.
