1/2 Clamp Brass Flow Sensor

GE-302E is 1/2" Clamp In-Line Water Flow Sensor, produced by Brass material, stability and sensitive, widely used in HVAC system, water heating system, water treatment system, to calculate the flow rate.

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.
