Product Details

Product description

Small Flow Hall Water Flow Sensor FM-HL3012-2 consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.  For example, installed flow sensor to the inlet end of the coffee machine to detect the rate of inlet water flow. when water passes through the flow rotor assembly,the magnetic rotor rotates and the rotating speed changes with the flow rate. Hall sensor outputs the corresponding pulse and feed back to the controller, which determines the flow range of water and regulates.
