Abstract:
1. A magneto-inductive flow measuring device, comprising: a measuring tube, through which a medium flows essentially directed along a measuring tube axis; a magnet arrangement, which produces an alternating magnetic field passing through said measuring tube essentially perpendicularly to said measuring tube axis; two measuring electrodes arranged essentially on a line directed essentially perpendicularly to said measuring tube axis and to the magnetic field; and a control/evaluation unit, which determines volume, or mass, flow of the medium flowing through said measuring tube on the basis of a measurement voltage tapped on said measuring electrodes, wherein: said control/evaluation unit determines a current, actual, settling time to reach a stable measurement state of the measuring device, compares the actual settling time with a desired settling time predetermined for the measuring device for reaching the stable measurement state, and generates an error report, when the actual settling time is greater than the predetermined, desired, settling time.
