2. Working Principle

The electromagnetic flow meter operates on the principle of electromagnetic induction. As a conductive fluid flows through the magnetic field within the meter, a voltage is generated. This voltage, proportional to the flow velocity, is detected by electrodes positioned on the pipe wall and converted into a flow signal.

Formula:
E = B · V · D · K
Where:

• E = Induced voltage
• B = Magnetic flux density
• V = Fluid velocity
• D = Distance between electrodes
• K = Calibration constant

The sensor transmits the signal to the converter, which processes it to display real-time and cumulative flow data. The system also supports outputs such as 4-20mA, frequency, and RS485 communication, with options for HART and MODBUS protocols.
