Abstract
A system and method for corrosion protection of measuring electrodes in electromagnetic flowmeters, wherein a respective constant direct current is generated by a current source for first and second metallic measuring electrodes provided on opposite sides of a measuring tube, and the constant direct current is passed from the current source to the first and second metallic measuring electrodes, where the constant direct current passed to each metallic measuring electrode is established to lower the electrode potential of a respective measuring electrode with respect to the medium below a threshold value to render the respective metallic measuring electrode immune to corrosion with respect to a medium.
