Electromagnetic flowmeters

KROHNE has been the market leader in the field of electromagnetic flow meters for 47 years. Thanks to the unique combination of high technology and the simplest user interface, Krohne electromagnetic meters are applicable in all areas of the industry. In the food and beverage industry, where fruit juices are mixed, milk with liquid hops, and then stuffed under sanitary conditions.

In the chemical and paper industries where Krohne electromagnetic meters are used in measuring acids, alkalis, pastes, as well as all other aggressive media. In the metal industry where liquids contain a high percentage of solids. It is not a stretch to say that PHYSIKALISCH-TECHNISCHE BUNDESANSTALT (PBT) uses precisely the KROHNE electromagnetic meters in its calibration systems.

Electromagnetic flow measurement is based on Faradey’s law. According to this law, voltage is induced in a conductive medium that moves in a magnetic field. This voltage is proportional to the flow rate of the medium. The transmitter amplifies that signal and converts it to standard outputs either current or pulse.
