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 inlet water flow. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate change. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller, which is controlled by the control. The device determines the size of the water flow and regulates it.

Features 1.The appearance of this product is light and handy, small in size, easy to install.
2.The stainless steel beads are set inside the impeller, which is always wear-resistant.
3. The high-quality brass with a content of more than 57% is resistant to temperature, pressure and aging, and the screw connection is tighter.
4. The imported Hall element is adopted, and the circuit is separated from the water. 5. All raw materials comply with ROHS testing standards.
