A method for determining the uncertainty of a measurement method of operating with a measuring frequency

摘要

Is shown and described a process for the determination of the uncertainty of a with a measuring frequency operating measuring method, in particular of a magnetically - inductive flow measurement method, wherein in each half cycle of the measuring frequency by scanning a measuring signal is determined in each case at least one measured value. Dollars a according to the invention, it is provided that the turbulence of the measured values in the case of the measuring frequency, however, for the measuring frequency is determined in a phase-shifted manner or / and in that the turbulence of the measured values in the case of at least two of the measuring frequency different frequencies is determined, and starting from the two irregularities in the case of the of the measuring frequency different frequencies to the action of the imbalance or imbalance of the measured values in the case of the measuring frequency is extrapolated or interpolated. In this way, a simple access to the balance wheel which is of interest as a diagnostic value made available at the measurement frequency.
