Description
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 flow of water. When the water passes through the water flow rotor assembly,
The magnetic rotor rotates and the speed changes with the flow rate, the Hall sensor outputs corresponding pulses
The signal is fed back to the controller, and the controller judges the size of the water flow and regulates it.
1. This product has a light and convenient appearance, small size, and easy installation.
2.The impeller is inlaid with stainless steel beads, which is always wear-resistant.
3. Circuit and water isolation design.
4. The Hall element is imported, and the valve body is made of transparent material for better observation of water flow and rotor conditions.
5. All raw materials meet ROHS testing standards
