Описание товара
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 .....
