Abstract: A magnetic-inductive flow meter and a method for operating such a magnetic-inductive flow meter for measuring the flow velocity or the volumetric flow rate of a medium in a measuring tube include subjecting the medium to magnetic fields of different polarity and field strength such that the changing between magnetic fields causes a voltage pulse in the medium and analyzing the voltage pulse to calculate a correction of an electrode voltage profile of a measuring electrode pair of the flow meter.

Abstract: The present disclosure relates to a method for measuring flow velocity or volume flow of a medium using a magneto inductive flow measuring device and to an arrangement having a magneto inductive flow measuring device, as well as to a filling plant with an arrangement, wherein the medium has a low conductivity. A high accuracy of measurement is achieved by provision of a first narrowing of a medium-containing pipeline and/or a second narrowing of a medium-containing measuring tube, wherein the pipeline leads the medium to a measuring tube of the flow measuring device.

Abstract: The present disclosure relates to a method for operating a magnetic-inductive flow meter for measuring the flow rate or the volumetric flow of a medium in a measuring tube and to such a flow meter, wherein the medium is acted upon by magnetic fields of different polarity and field strength, wherein the alternation between magnetic fields causes a voltage pulse in the medium, wherein a voltage pulse during a phase without a magnetic field is used for calculation of a correction of an electrode voltage characteristic.

Abstract: A magneto-inductive flow measuring device for ascertaining flow of a measured medium through a measuring tube having a measuring tube axis, comprising: at least a first coil component having a coil body for accommodating a coil core of a coil. The coil is wound on the coil body and the coil core is arranged in a first passageway of the coil body with a longitudinal axis of the coil core coaxial with the coil. At least two cable strands are arranged between the coil core and the coil body, wherein the cable strands serve for tapping the signal of two or more measuring electrodes arranged on the measuring tube. The cable strands extend within the coil component essentially along a cutting plane, which extends perpendicular to the measuring tube axis.
