When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate, and the Hall sensor outputs corresponding pulses. _x000D_ The signal is fed back to the controller, and the controller judges the size of the water flow and regulates it. _x000D_ _x000D_ Note: _x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
