A magnetic flow meter, or mag meter, is a volumetric flow meter with no moving parts and is ideal for wastewater applications or any other dirty liquid that is conductive. Magnetic flow meters will generally not work with hydrocarbons, distilled water, or many non-aqueous solutions.

Magnetic Water Flow Meter is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm. Based on Faraday’s law of electromagnetic induction. Magnetic Water Flow Meter is ideal for wastewater applications or any dirty liquid which is conductive or water based.

A magnetic flow meter (mag meter, electromagnetic flow meter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines.

Mag meters operate under the principle of Faraday’s Law of Electromagnetic Induction to measure liquid velocity. The principle of operation states that a conductor moving through a magnetic field produces an electric signal within the conductor, which is directly proportional to the velocity of the water moving through the field.

Electromagnetic flow meters or magmeters are used for measurement in water and wastewater industry. Meter installations in large water lines is quite expensive. This is where insertion magnetic flow meters can make a difference. They are inexpensive and assure accurate flow measurements.
