The electromagnetic flowmeter operates based on Faraday’s law of electromagnetic induction. Two electromagnetic coils at the upper and lower ends generate a magnetic field. When conductive fluid passes through the meter, an electromotive force (E) is induced between the electrodes on the flow tube wall, proportional to the flow velocity (V), magnetic flux density (B), and electrode spacing (D).
Induced Voltage Formula:
E = K × B × V × D
Where:
-
E – Induced electromotive force
-
K – Meter tube constant
-
B – Magnetic flux density
-
V – Average flow velocity
-
D – Electrode spacing
The induced voltage signal is transmitted to the converter for analog and digital processing. The instantaneous flow and totalized flow are then displayed on the converter’s screen.
