As early as 1832, Michael Faraday tried to determine the speed of the current in the Thames by measuring the voltage induced in flowing water by the earth`s magnetic field. Electromagnetic flow measurement is based on Faraday`s law of induction. According to this law, a voltage is induced when an electric conductive fluid flows through the magnetic field of an electromagnetic flowmeter. This voltage is proportional to the flow velocity of the medium. 

The induced voltage is picked up either by two electrodes in contact with the medium or by capacitive electrodes with no contact to medium and supplied to a signal converter.
A signal converter amplifies the signal and converts it into a standard signal (4-20 mA) as well as to a frequency/pulse signal(e.g. one pulse for every cubic meter of measured medium that flows through the measuring tube). 

As founder and world market leader in electromagnetic flowmeter technology,we have been impressing our customers with innovation for more than 60 years, innovations that continue to set the standard for the competition.
Our OPTIFLUX product line is an excellent example of this: a converter for all applications. A one-of-a-kind diagnostics package that can even look into the process. An intuitive operating concept featuring a quick start function for simple start-up.
Thanks to this unique combination of high-end technology and maximum user-friendliness, you will benefit in a wide range of industries: in the food and beverage industry, where fruit juices, milk and liquid hops must be mixed, dosed and filled under hygienic conditions. In the chemicals industry and in the pulp and paper industry, where our devices deal with acids, alkalis, pastes, sludges and other caustic media, or in the metal and mining industry where media with a high solid content are encountered on a daily basis.
We produce electromagnetic flowmeters in our plants in the Netherlands, Brazil, India and China. It is no wonder that the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany, relies on electromagnetic flowmeters from KROHNE in their calibration systems.
