Patent ID: 8307719

Claim:
An apparatus for measuring volume- or mass-flow of a medium in a pipeline, comprising: a measuring tube, through which medium flows in the direction of said measuring tube axis, wherein the measuring tube has, in the stream direction of the medium, a first end region and a second end region; a magnet system, which produces a magnetic field passing through said measuring tube essentially transversely to the direction of said measuring tube axis; loose flanges; at least one measuring electrode coupled with the medium and arranged in a region of said 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 said measuring tube on the basis of a measurement voltage induced in said at least one measuring electrode, wherein: said measuring tube is embodied as one-piece; said first end region and said second end region of said measuring tube are flared; and said flared end regions of said measuring tube serve as axial stop surfaces for said loose flanges, via which said measuring tube is securable in the pipeline.
