YF-S201 Water Flow Sensor/4 Points G1/2 Interface Water Heater Water Dispenser Water Dispenser Hall FlowmeterItem NO.: YF-S201

YF-S201 Water Flow Sensor

Product Description:

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