Electromagnetic water meter LXE-100

The flow measurement principle of electromagnetic water meter is based on Faraday’s law of electromagnetic induction:

When the conductive liquid flows through the measuring tube in the magnetic field, it produces a flow perpendicular to both the direction of flow and the magnetic field, which is proportional to the average velocity

Proportional induced electromotive force. The electromagnetic water meter consists of two parts: the sensor and the converter, which transmits the excitation current to the wire inside the sensor

The circle generates a magnetic field inside the sensor’s measuring tube. The conductive liquid flowing through the tube induces an electromotive force by cutting the magnetic field lines. Electrodes fixed on both sides of the tube wall receive this induced electromotive force and transmit it to the converter via signal cables. The converter filters, amplifies, processes, and transforms the signal to determine the flow rate of the measured medium.

Finally, the converter output is a standard current signal or frequency signal proportional to the flow measurement value.
