G1/2 Water Flow Sensor Flowmeter Hall Flow Meter 4 Wire With Temperature Sensing

Introduction:

This water flow sensor is mainly composed of a plastic valve body, the flow of rotor components and a hall sensor. It is installed in the water heater inlet, which used to detect water flow, when the water pass through flow rotor components, magnetic rotor rotation and speed changes with the flow, hall sensor output pulse signal and feedback to the controller to judge the size of the water flow, for control.

Feature:

This product appearance light and agile, small size,easy to install
Inlaid with stainless steel impeller shaft, always wear-resistance
The seal with the upper and lower force structure never leaks
The Hall element is imported from German,and use potting package, prevent water and never aging
All of this raw materials are all in accord with ROHS testing standards
