Abstract
An electromagnetic flowmeter for mass flow measurement of a flowing medium having a measuring tube, a magnetic field generator for generating a magnetic field at least partially passing through the measuring tube, having two electrodes for tapping into a measurement voltage induced in the flowing medium and having a housing incorporating the measuring tube, the magnetic field generator and the electrodes, wherein the measuring tube has a cross section that varies along its length and the cross section in the mid-section of the measuring tube is smaller than at its ends, preferably the cross section of the measuring tube being rectangular in its mid-section, optionally also square, and wherein the housing preferably has a circular cross section. At least one reinforcement, preferably two, is provided in the mid-section of the measuring tube joining the measuring tube and the housing.
