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. It does not have any moving parts to wear down, reducing the need for maintenance or replacement. 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 delivers accurate, pressure-drop-free, volumetric flow measurements of liquids, slurries, pastes, and other electrically conductive media. A range of liner materials, electrode options, line sizes, battery-powered type and flange pipelines, accommodate a wide variety of process applications. Holykell is committed to cost-effective and optimized solutions, offering a range of integrated type, split type, full bore and insertion-style mag meters suitable for agriculture, municipal, industrial, and even oil and gas applications. OEM and ODM order is accepted.
