General

Electromagnetic flow measurement has been in use around the world for 50 years and more, as witnessed by the popularity of these meters that continues unabated in virtually all sectors of industry.

 

Electromagnetic flowmeters can be used to measure all electrically conductive liquids (> 5 µS/cm) with or without solids, e.g. water, wastewater, sludge, slurries, pastes, acids, alkalis, juices, fruit pulp, etc.

 

In the industrial environment, sectors that utilize this measuring principle include: water/wastewater, chemicals, pharmaceuticals, pulp and paper, foodstuffs, etc. Electromagnetic flowmeters are even robust enough to be used in mining.

Transmitters

Unified operating concept, flexible outputs, software packages, Fieldbus interface, Ex-approvals and much more - all a matter of course for the Promag transmitters.
