Magnetic-inductive flowmeter and corresponding method

A method for determining an axial flow speed distribution for a magnetic-inductive flowmeter comprising a measuring tube, at least one coil pair and at least one measuring electrode with an electrode head, wherein the measuring tube comprises an inflow section and an outflow section which are spaced to one another in an axial direction of the measuring tube, wherein the measuring tube has at least one opening on a circumferential wall thereof, wherein the electrode head of the at least one measuring electrode is arranged in the at least one opening, wherein the at least one coil pair is provided with a first coil and a second coil, wherein the first and second coil of the at least one coil pair are arranged offset with respect to one another in the axial direction of the measuring tube on the circumferential wall of the measuring tube, wherein the first and the second coil are arranged at least partially overlapping one another in a top view of a cross section through the measuring tube, and wherein the at least one measuring electrode is arranged on a peripheral area of the circumferential wall of the measuring tub that is located between the first and the second coil of the at least one coil pair, wherein the method comprises operating the flowmeter using a DAR method using a weighting function that contains an iterative method.
