Abstract
The present disclosure relates to a magnetic-inductive flowmeter for measuring flow velocity of a medium, comprising a measuring tube; an apparatus positioned toward a cross-section of the measuring tube for producing a magnetic field extending perpendicular to a longitudinal direction, wherein the apparatus includes a segment coupling the magnetic field into the medium, wherein the segment surrounds the measuring tube over a first angle; and an electrode system having at least two electrode pairs adapted to register a voltage induced in the medium, wherein a second angle defines a minimum circular sector in which the electrodes located on one side of the measuring tube are distributed, wherein first and second angles are so matched to one another that the flowmeter is insensitive to departures from a rotationally symmetric flow such that the flowmeter in a test measurement has a measurement error of flow velocity less than 1.0%.
