Abstract
A method for online-determination of at least one characteristic value of a mass flowmeter operating by the Coriolis principal and incorporating a fluid-conducting Coriolis conduit. The method includes the following steps of exciting the Coriolis conduit in a first oscillation pattern, exciting the Coriolis conduit in a second oscillation pattern, the second oscillation pattern being different from the first oscillation pattern, capturing the response of the Coriolis conduit to the excitation in the first oscillation pattern and in the second oscillation pattern and determining at least one characteristic value of the mass flowmeter by evaluating the response of the Coriolis conduit with the aid of a model in real time during operation of the mass flowmeter.
