Plastic Water Flow Sensor

The flow sensor have both end male thread, the size could be BSP1/2" BSP3/4" BSP1" DN32 DN40 DN50. produced by PA66 plastic material, stability and sensitive, widely used in HVAC system, water heating system,  to calculate the flow rate. CE certification.

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.
