Water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine. 

Life is longer than plastic body.


• Compact, Easy to Install

• High Sealing Performance

• High Quality Hall Effect Sensor

• RoHS Compliant
