Description

Firstly, The Water Flowmeter Sensor 1-30L/min works on the principle of “Hall Effect”. According to which, a voltage difference is induced in a conductor transverse to the electric current and the magnetic field perpendicular to it. Hence, Hall Effect is utilized in the flow meter using a small fan/propeller shaped rotor which is placed in the path of the liquid flowing.

The liquid thus pushes against the fins of the rotor, causing it to rotate. The shaft of the rotor is connected to a hall effect sensor. It is an arrangement of a current flowing coil and a magnet connected to the shaft of the rotor. Thus a voltage/pulse is induced as this rotor rotates. This is due to the changing magnetic field caused by the magnet attached to the rotor shaft, as seen in the picture below. Accordingly, We measure the number of pulses using any microcontroller such as Arduino.
