    Product Tags


    The water flow sensor is mainly composed of plastic valve body, water flow rotor assembly and hall sensor.

    It is installed at the inlet end of the water heater to detect the inflow flow. When water flows through the rotor assembly,

    The magnetic rotor rotates and the rotational speed varies with the flow rate, and the hall sensor outputs corresponding pulses Signal, feedback to the controller, by the controller to judge the size of the water flow, regulation.


    1. This product is light and convenient in appearance, small in size and easy to install.

    2. The impeller is inlaid with stainless steel beads, which is always wear-resistant.

    3. The sealing ring used on, under the force of the structure will never leak.

    4. Hall components imported, and with waterproof apron silicone reinforcement to prevent water, never aging.

    5. All raw materials meet ROHS testing standards.

    6. Standard g1/2 screw tooth interface is more simple and firm.
