Business- and engineering firm with focus on processinstruments
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.
