CORIOLIS MASS FLOW METER AND METHOD FOR DETERMINING VARIABLES INFLUENCING THE TOTAL ZERO POINT ERROR OF THE METER, METHOD FOR DETERMINING THE TOTAL ZERO POINT ERROR AND OPERATING METHOD FOR SAME

A method for determining variables influencing a total zero point error of a Coriolis mass flow meter comprises: exciting a vibration of a bending vibration mode; measuring a first total zero point error T at a flow of zero; ascertaining a first damping value D of the vibration of the bending vibration mode; measuring an exciter-independent zero point error I during a decaying vibration of the bending vibration mode at a flow of zero; ascertaining a first exciter-dependent contribution E to the first total zero point error T based on the first total zero point error T and based on the exciter-independent zero point error I; and ascertaining a sensitivity factor S for the bending vibration mode based on the first exciter-dependent contribution E to the total zero point error T and based on the first damping value D.
