It works on the principle of electromagnetic induction (Faraday’s law): when a conductive fluid passes through a magnetic field, a voltage proportional to the flow velocity is generated. The on-board electronics convert that signal into a volumetric flow reading. There are no moving parts in contact with the fluid, which ensures a long service life and reduced maintenance.

All conductive liquids, including water, chemical fluids and industrial solutions, even corrosive or abrasive ones, provided they fall within the conductivity limits stated by the manufacturer (generally ≥ 5 µS/cm). It is not suitable for non-conductive fluids such as pure hydrocarbons, gases or steam.

A magnetic meter measures volumetric flow and is ideal for conductive liquids at a contained cost. A Coriolis meter measures mass flow and density and works with almost any fluid, including non-conductive ones, but is more expensive. For water, chemical solutions or conductive process fluids, the magnetic meter is generally the best choice.

Magnetic flow meters typically offer an accuracy of ±0.2–0.5% of reading. The actual accuracy depends on correct installation (straight runs upstream and downstream), selecting the DN appropriate to the flow rate, the conductivity of the fluid and the model chosen. Our technical team supports you in selection and correct sizing.

No. The operating principle requires the fluid to have a minimum electrical conductivity (generally ≥ 5 µS/cm). For non-conductive fluids such as hydrocarbons, oil or gas, Coriolis, Vortex or ultrasonic meters are more suitable. Contact us for an analysis of your process.
