Water Flow sensor comprises of a plastic body housing, a water rotor, a hall-effect sensor and PCB electronics board.
Working performance : When the water flows through the rotor, the rotor spins and its speed changes with different rate of flow. The rotor creates a signal at Hall sensor and the hall-effect sensor outputs the corresponding pulse signal .
By Counting the pulse rate the flow of fluid can be measured.
This flow sensor is suitable for detecting the flow in water dispenser or coffee machine etc…..
