Method for determining a characteristic quantity for correction of measured values of a Coriolis mass flowmater

The invention relates to a method for determining at least one characteristic variable for the correction of measured values ??of a Coriolis mass flowmeter. Furthermore, the invention relates to a Coriolis mass flowmeter having at least one measuring tube, at least two sensors and at least one actuator, wherein the measuring tube to the actuator to at least one oscillation can be excited.

A method for determining at least one parameter for the correction of measured values ??of a Coriolis mass flow meter, which is characterized by an increased accuracy and improved reliability in the determination of the characteristic is realized by the following method steps comprising:

- Detecting values ??of a measured variable at constant flow with the transducers,

- Calculating at least one location parameter from the detected values,

- Calculating at least one scattering parameter of the detected values ??and the location parameter,

- Detecting said additional values ??and calculating scattering parameters and position parameters of the existing and additional values ??is carried out frequently, and the dispersion parameter reaches a threshold value as a selection criterion, and

- Wherein the location parameter corresponding to the scattering parameter is used as a parameter for the correction of the measured values ??of the Coriolis mass flowmeter.
