An apparatus for measuring volume- or mass-flow of a medium in a pipeline. The apparatus includes: a measuring tube, through which medium flows in the direction of the measuring tube axis, wherein the measuring tube has, in stream direction of the medium, a first end region and a second end region; a magnet system, which a produces a magnetic field passing through the measuring tube essentially transversely to the measuring tube axis; at least one measuring electrode coupled with the medium and arranged in a region of the measuring tube lying essentially perpendicular to the magnetic field; and a control/evaluation unit, which delivers 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. In order to keep costs for the magneto-inductive flow measuring device low, the measuring tube is embodied as one-piece and the first end region and the second end region of the measuring tube are flared. |
