Water Flow sensor is basically used to take a note of how much water has been transferred from one area to the other. Water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When water flows through the rotor, the rotor start rolling after feeling the pressure. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.


Nowadays water flow sensor is used in wide variety of areas. Some common Examples are: Water Management, Mining and Extracting, Agriculture, etc.
