    Abstract: A magnetic-inductive flow meter includes: a measuring tube for guiding a flowable medium in a longitudinal direction; a measuring electrode arrangement for detecting a measurement voltage dependent on the flow velocity, induced in the medium, two measuring electrode groups opposite one another on the measuring tube; and a magnetic field generating device for generating a magnetic field which passes through the measuring tube and including at least two coil core groups, each having at least two coil cores, wherein a first and a second part of the measuring tube each include at least one coil core group, wherein two radii, which intersect the coil cores of a coil core group that lie externally in a cross-sectional plane of the measuring tube, enclose a centre angle β by which 80°≤β≤105°.

    Abstract: A magnetically inductive flowmeter includes a measuring tube having a tube axis and a tube wall; a magnet system for producing a magnetic field that extends perpendicularly to the tube axis; at least one pair of measuring electrodes for sensing an electrical voltage induced in the medium by the magnetic field; and an electronic measuring/operating circuit for operating the magnet system and the measuring electrodes. The magnet system includes a coil system having a coil having a coil core and further includes two pole shoes. The coil system includes a field guide-back, wherein a tangential fraction of the magnetic field in the coil relative to the measuring tube axis amounts to at least 90% of the total magnetic field. The field guide-back has a guide-back part that extends through the coil and forms the coil core of the coil.
