Description

1/2" Water Flow Sensor Switch With Temperature Detection For Turbine Liquid Sensor, Hall Flow Meters, Copper Shell
Features:
ROHS standards: The water flow sensor is mainly composed of copper valve body, water flow rotor assembly and Hall sensor. Raw materials meet ROHS standards.
Principle: Installed at the water inlet end of the water heater, it is used to detect the water inflow. When water passes through the water flow rotor assembly, the magnetic rotor rotates and the rotation speed changes with the flow change. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller, and the controller judges the water inflow and regulates it.
Sealing Property: seal each hole, and add 1.7Mpa water pressure test for 1 minute without leakage and deformation.
Application: water heater, broiler and heat pump, etc.
The package: 1* Water flow sensor(With temperature probe).
