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. The physical principle at work is electromagnetic induction. The magnetic flow meter requires a conducting fluid, for example, water that contains ions, and an electrical insulating pipe surface, for example, a rubber-lined steel tube.
If the magnetic field direction were constant, electrochemical and other effects at the electrodes would make the potential difference difficult to distinguish from the fluid flow induced potential difference. To show this in modern magnetic flowmeters, the magnetic field is constantly reversed, cancelling out the electrochemical potential difference, which does not change direction with the magnetic field. This however prevents the use of permanent magnets for magnetic flowmeters.

Electromagnetic water meter ‘s measurement is advanced. The faster the flow of the fluid, the greater the voltage signal generated. Electrode sensors located on the flow tube walls pick up the voltage signal and send it to the electronic transmitter,which processes the signal to determine liquid flow.

Q&T Instrument was established in 2005, products including mag flowmeter, turbine flow meter, ultrasonic flow meter, thermal mass flow meter, etc

Electromagnetic flowmeters (mag meters) are volumetric flow meters that take measurements by generating a magnetic field that channels through conductive liquids as they flow through a pipe. As the fluid flows, the voltage electrodes in the pipe wall sense the voltage. The higher the flow rate, the greater the amount of voltage generated. An electronic transmitter then converts these signals to provide flow rate measurements.
Use electromagnetic flowmeters with virtually any conductive liquid, including abrasive slurries, water, wastewater, chemicals, acids, and contaminated fluids. These meters are not compatible with steam, gas, oil, or nonconductive fluids.
