This water flow sensor is mainly composed of a plastic valve body, the flow of rotor components and a hall sensor. It is installed in the water heater inlet, which used to detect water flow, when the water pass through flow rotor components, magnetic rotor rotation and speed changes with the flow, hall sensor output pulse signal and feedback to the controller to judge the size of the water flow, for control.
