Abstract
In a method for determining mass-flow with the aid of a Coriolis mass-flow meter in which mass-flow ({dot over (m)}) is won from the phase difference of two sensor signals X, X, three measuring channels K, K, Kare provided for the two sensor signals X, X. By selective switching of the sensor signals X, Xonto the measuring channels K, K, K, phase error caused by the different signal paths can be determined and taken into consideration when calculating mass-flow ({dot over (m)}).
