mag-flux A

Magnetic-inductive sensor for a wide range of applications

Our magnetic-inductive sensors (MID) are precision measurement devices and suitable for linear flow measurement of almost all electrically conductive liquids, as well as slurries, pulps and pastes. Thanks to the magnetic field’s properties, these devices can be used for flow speeds up to 10 m/s (32.8 ft/s) and for a minimum conductivity of 20 / 3 µS/cm.

The flow meter consists of a sensor and a corresponding measuring transducer. They are available both in separate and in compact designs.

Area of application:

The key applications for the mag-flux A magnetic-inductive sensor (MID) are in flow measurement of electrically conductive liquids such as e.g. water, pulps, pastes, slurries, acids, solvents, lyes, emulsions, or slurries, sand or water mixes, including liquids with a minimum conductivity of 20 / 3 µS/cm.

The magnetic-inductive flow meter is used in the following industries:

Plant and mechanical engineering
Fire safety
Chemicals
Building services equipment
Foodstuffs
