Abstract
A method for monitoring oscillation characteristics in a Coriolis, flow measuring device and to a correspondingly formed, Coriolis, flow measuring device in the case of which an excited oscillatory system is simulated with a digital model, which has at least one fittable parameter. The simulating includes, in such case, excitating the digital model in the same manner as the oscillatory system, calculating a simulation response variable of the simulated oscillations according to the digital model, and, performed over a plurality of signal modulations, iterative conforming of the at least one, fittable parameter in such a manner that the simulation response variable interatively approaches the response variable. Furthermore, it is ascertained whether a corresponding limit value is exceeded by the at least one, interatively ascertained parameter value for the at least one, fittable parameter or by at least one variable derived from the at least one, iteratively ascertained parameter value.
