Flow Sensor  MR168







Introduction: flow sensor consists of magnetic core, rotating impeller, external casing and sensor. 

Flow through the sensor activates the magnetic core to trigger switch action, with signal output.


Features: imported components of the magnetic switch, sample working principles, and highly reliable, cheaper price.


Applications: it is used in the control of water circulation, water charging and discharging, water heating, 

water pump switch on and off of solenoid valve, or powering on and off of water discharging for electric water heater, 

solar energy water heater, air condition and other water systems.
