Feature

●The water flow sensor is mainly composed of a aluminum alloy valve body, a water flow rotor assembly, a steady flow assembly and a Hall element.
●It is installed at the water inlet end of the water heater to detect the flow rate of the inlet water.
●When the water passes through the water flow rotor assembly, the magnetic rotor rotates, and the speed changes linearly with the flow rate.
●The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller.
●The controller judges the size of the water flow and regulates it.
