摘要
A magneto-inductive flow measuring device is disclosed that includes a measuring tube with a measuring tube axis and two measuring electrodes arranged diametrally opposite one another on the measuring tube and from which a signal is tapped for ascertaining a flow. The flow measuring device includes four other electrodes in pairs arranged diametrally opposite one another on the measuring tube, forming second and third electrode axes that intersect the measuring tube axis, where the two electrode axes are arranged offset from a parallel projection of the first electrode axis onto the second cross-sectional plane by a clockwise or counterclockwise angular measure. The flow measuring device further includes an evaluation unit for detecting a flow profile based on measurement signals tapped from the electrodes of the two electrode axes. A further aspect of the disclosure includes a method for compensating a flow profile related measurement error in a flow measurement.
