Water flow sensor is mainly composed of plastic valve body, flow of rotor components and hall sensor.
It is installed in the water heater inlet, used to detect water flow, when the water through flow rotor components.
Magnetic rotor rotation and speed changes with the flow, hall sensor output pulse accordingly.Signal feedback to the controller by the controller to judge the size of the water flow, adjust and control.
1.This product appearance is light and agile, small volume, easy to install.
2. Internal set with stainless steel shaft, impeller, wear forever.
3. Sealing ring, the force of the structure under never leak.
4. Hall element, USES the German import and encapsulated with potting glue, prevent water, never aging.
5. All raw materials meet ROHS testing standards.
