On following the principle of Hall Effect, our product has settled lots of technic defects wih advanced controlling method to detect water flow. It is compact sized with low starting level, featuring in stable performance, accurate measurement, acute reaction, convenient access, and etc.
When the water flow pushes the rotor, its magnet shall generate a rotating magnetic field; and then the Hall sensor will find a pulse signal from the magnetic field transformation, and then deliver it to the output control circuit after transformation. The signal pulse frequency and water flow is proportional.
