ABSTRACT:
An apparatus for measuring volume- or mass-flow of a medium flowing through a measuring tube in the direction of the measuring tube axis, and includes: a magnet system, which produces a magnetic field passing through the measuring tube essentially transversely to the measuring tube axis; at least one measuring electrode, which contacts the medium in a defined surface region; and a control/evaluation unit, which provides information concerning volume- or mass flow of the medium in the measuring tube on the basis of a measurement voltage induced in the at least one measuring electrode. At least the medium-contacting surface region of the at least one measuring electrode is manufactured of a chemically inert and electrochemically and mechanically resistant material.
