Measuring principle
The electromagnetic flow meter uses advanced low-frequency square wave excitation. According to Faraday’s law of electromagnetic induction, two coils located at the top and bottom of the measurement tube generate a constant or alternating magnetic field. When conductive liquid flows through the sensor, an induced voltage is generated between the two electrodes mounted on the tube walls. The induced voltage is proportional to the flow velocity, magnetic field strength, and pipe diameter:
Where:
-
E – Induced voltage
-
K – Instrument constant
-
B – Magnetic flux density
-
V – Average flow velocity in the measurement tube
-
D – Internal diameter of the measurement tube
The induced voltage is detected by electrodes and transmitted via cable to the converter. After analog and digital signal processing, instantaneous and cumulative flow are displayed on the converter screen. Flow measurement is independent of flow direction, ensuring accurate bidirectional readings.
