Conductivity

Electromagnetic flowmeters provide a number of advantages over other flow measurement technologies including excellent accuracy & repeatability, wide turndown ratios, long service life, and low/no pressure loss. One key consideration when sizing and specifying Mag Meters is that the fluid media must be electrically conductive; typically ≥ 5μS/cm. In order to assist users of Electromagnetic Flowmeters with the task of determining if a mag meter will work in their given application. 

Smartmeasurement has compiled an industry-leading reference for electrical conductivities of various fluids. In the table below, conductivity values shown in green indicate that the corresponding fluid is suitable for use with a mag meter.   If the conductivity value is red, a mag meter is not suitable and alternate flow measurement technologies should be explored. Conductivity values displayed in yellow are questionable; please contact the SmartMeasurement factory for assistance.

If a particular chemical is not listed, or if you would like application assistance with an electromagnetic flowmeter application, please feel free to contact SmartMeasurementTM’s U.S. offices at 1-866-404-5415 for assistance. Our team of application engineers would be happy to review your application and quote a suitable mag meter at industry-leading prices. 

There are 228 different materials listed in the conductivity table below. Green numbers indicate high conductivity fluids suitable for magnetic flowmeters. Orange numbers indicate low conductivity and may not lead to successful applications. Red numbers warn that conductivities are too low to use magnetic flowmeters.
