The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor.
It is installed in various coffee machines, water dispensers, and water inlets of electrolyzers to detect the influent flow. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the rotational speed changes with the flow rate. The Hall sensor outputs the corresponding pulse. The signal is fed back to the controller, and the controller determines the magnitude of the water flow and performs regulation.
