Abstract

A method for operating a Coriolis mass flow measuring device having at least one measuring pipe through which a medium flows, at least one vibration generator, at least a first vibration sensor, at least a second vibration sensor and at least a control and analyzing unit. The detection of measurement variables or diagnosis parameters is achieved with increased accuracy and security in that the control and analyzing unit calculates, at least indirectly and in a ratiometric manner, at least a derived secondary variable based on a primary measurement, wherein interested primary measurement signals are transmitted alternately to the control and analyzing unit via different measurement channels and wherein, based on the various values obtained from the different measurement channels regarding the primary measurement signals, compensation values of the transmitted primary measurement signals are calculated and used as a basis for the calculation of the derived secondary variable.
