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 flow meters are often selected and specified for applications because they are obstruction-less, cost-effective for aggressive chemicals and slurries, and provide highly accurate volumetric flow measurement. A range of liner materials, electrode options, and line sizes accommodate a wide variety of process applications.

Operation Theory

Magnetic flow meters utilize Faradayrsquo;s Law of Electromagnetic Induction to determine the velocity of a liquid flowing through a pipe. Faradayrsquo;s Law forms the basis for electrical generation systems where wires travel through a magnetic field and produce a voltage.In magnetic flow meters, a magnetic field is generated and channeled into the liquid flowing through the pipe.
To accomplish this, the electromagnetic coils can be located outside of the pipe (flow tube), however, the flow tube must be non-magnetic to allow penetration of the magnetic field into the liquid.

Locating the coils internal to the flow meter (closer to the liquid) can reduce the electrical power necessary to deliver the magnetic field, as well as reduce the size of the flow meter and fabrication costs.

Following Faradayrsquo;s Law, the flow of a conductive liquid through the magnetic field will cause a voltage signal to be generated. This signal is sensed with electrodes located on the flow tube walls. When the coils are located externally, a non-conductive liner is installed inside the flow tube to electrically isolate the electrodes and prevent the signal from being shorted. For similar reasons, non-conductive materials are used to isolate the electrodes for internal coil designs. The fluid itself is the conductor that will flow through the magnetic field and generate a voltage signal at the electrodes. When the fluid moves faster, more voltage is generated.Faradayrsquo;s Law states the voltage generated is proportional to the movement of the flowing liquid.The transmitter processes the voltage signal to determine liquid flow.
