Abstract
A method for determining at least one characteristic for the correction of measurements of a Coriolis mass flowmeter which is characterized by an increased accuracy and a low error rate while determining the characteristic is implemented by detecting values of a measurand during constant flow with the reading sensors, calculating at least one location parameter from the detected values, an calculating at least one dispersion parameter from the detected values and the location parameter. The detection of additional values and the calculation of the location parameter and dispersion parameter from the existing and additional values is carried out until the dispersion parameter reaches a threshold value, and then, the location parameter corresponding to the dispersion parameter is used as the characteristic for the correction of the reading of the Coriolis mass flowmeter.
