When a flowing conducting fluid with instalasi flow meter is subjected to a transverse magnetic field, the flowing conducting fluid cuts the magnetic field and causes a voltage to be induced. This induced voltage is proportional to the fluid velocity, that is, flow rate. ConstructionThe main parts of this instrument are as follows:
This magnetic flow meter is based on Faraday's law of induced voltage which is given as follows, E = BLV B = flux density (Gauss) L = Length of conductor which is the diameter of the pipe (cm) V = Average velocity of conductor (fluid) in cm/sec When the conducting fluid flows through the pipe which is subjected to a magnetic field, the conducting fluid cuts the magnetic field and due to this a voltage is induced. As the magnetic field is constant, voltage obtained across the electrodes will be directly proportional t average fluid velocity and diameter (length) and hence becomes a measure of volume flow rate.
