Water flow sensor is mainly composed of plastic body, the flow of rotor components and hall sensor.
It is placed in the water heater inlet, used to detect water flow, when the water through the water flow rotor components, magnetic rotor rotation and speed changes with the flow, hall sensor output pulse signal, the corresponding feedback to the controller, the controller to judge the size of the water flow, adjust and control.
