how to choose electromagnetic flow meter

Electromagnetic flowmeter is based on the principle of electromagnetic induction, through the electromotive force generated by the conductive fluid through the external magnetic field to measure the fluid flow meter. Electromagnetic flowmeter is widely used because of its high precision and good stability, so the choice of integrated or split electromagnetic flowmeter is particularly important.

The grounding of the electromagnetic flowmeter is equipped with a grounding ring, and then the grounding ring is connected to the pipeline. If it’s lined, you need a third electrode to ground it.

Electromagnetic flowmeter as a commonly used flow measurement instrument, the choice of its material is also an important factor. Because in the electromagnetic flowmeter, the part in contact with the medium is only the electrode and the inside of the measuring tube, it is necessary to select the correct electrode and lining material according to the characteristics of different media.

Electromagnetic flowmeter selection is generally more concerned with the measurement medium, temperature, pressure, connection form, protection level and whether explosion-proof.
