ABSTRACT:
An apparatus for measuring volume- or mass-flow of a medium in a pipeline. Included is a measuring tube, through which the medium flows in the direction of the longitudinal axis of the measuring tube; a magnet system, which is embodied in such a manner, that it produces a magnetic field passing through the measuring tube essentially transversely to the longitudinal axis of the measuring tube; at least one measuring electrode coupled with the medium, which is arranged in a bore in the wall of the measuring tube in a region lying essentially perpendicular to the magnetic field. The measuring electrode has an elongated electrode shaft having a first widened end region, which is so dimensioned, that its diameter larger is than the diameter of the bore in the wall of the measuring tube, in which the measuring electrode is placed; and a control/evaluation unit, which, on the basis of a measurement voltage induced in the at least one measuring electrode, delivers information concerning volume- or mass-flow of the medium in the measuring tube. In the opposing, second, end region of the electrode shaft of the measuring electrode, at least one radial recess or at least one radial protrusion is arranged. Furthermore, a binding-element is provided, which is so embodied, that it fixes the measuring electrode in the bore of the measuring tube in the axial direction by engaging with the at least one radial recess or protrusion.
