G1/2" Brass Hall Flow Rate Meter NTC Temperature Measurement Water Flow Sensor

Description

G1/2" Brass Hall Flow Rate Meter NTC Temperature Measurement Water Flow Sensor
Product Description :
Water Flow sensor includes  a plastic/brass body housing,  a water rotor, and a hall-effect sensor, PCB electronics board.
Working performance : When the water flows through the rotor, then rotor is rolled.
Its speed changes with different rate of flow. Then the magnetic rotor make reaction to Hall sensor,the hall-effect sensor outputs the corresponding pulse signal .
The flow sensor is suitable to detect the flow in water dispenser or coffee machine .....
