Description

The water flow sensor is mainly composed of a copper valve body, a water flow rotor assembly and a Hall sensor. Installed on the water inlet end of the water heater to detect the water flow rate. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. Judge the size of the water flow and adjust it.
