Verfahren und Vorrichtung zur Ermittlung der Füllqualität eines Biegeschwingers

A method determines the filling quality of a frequency oscillator where a measured fluid is passed through an oscillator tube. The relationship between the viscosity-dependent density of the measured fluid and the quality and/or attenuation of the oscillator tube is determined. The relationship between the dynamic viscosity and the attenuation and/or quality of the measured fluid is determined, and these values are used to create a calibration table that reproduces the functional relationship between a parameter relevant for the quality and/or the attenuation of the frequency oscillator and the viscosity of the measured fluid. An independent measuring apparatus determines a measured value for the dynamic viscosity of the measured fluid. The obtained measurement value for the viscosity coincides in the calibration table with a specific function value, and the result of this comparison with respect to the presence of any filling errors is used to determine a possible filling error.
