ME2300 Electromagnetic Flow Meter (mag meter, electromagnetic flowmeter, electro-magnetic flowmeter) is a device used to measure the volumetric flow rate of a liquid or a gas. It is also known as a magnetic flow meter or an EMF meter. Electromagnetic flow meters are used to measure many types of liquids including water, wastewater, chemicals, and other liquids.

Mechelex Instruments Electromagnetic flow meters measure the flow of a liquid or gas by detecting the magnitude and direction of the magnetic field generated by the flow of the liquid or gas through the meter. The flow rate is then calculated by the electromagnetic flow meter based on the magnitude and direction of the magnetic field.
