Features:
1. This product is light and handy in appearance, small in size, and easy to install.
2.There is a stainless steel shaft inside the impeller, which is always wear-resistant.
3.The sealing ring adopts the structure of upper and lower force and never leaks.
4. The Hall element is imported from Germany and is encapsulated with potting glue to prevent water ingress and never age.
5. All raw materials meet ROHS testing standards
1. Product introduction:
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 the water inlet. 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
The signal is fed back to the controller, and the controller judges the size of the water flow and regulates it.
