Abstract
A method for operating a Coriolis mass flowmeter in which the interferences when calculating the medium parameters is considered by the eigenfrequency (f) of the oscillation of the measuring tube being determined in the first and second natural modes during operation of the Coriolis mass flowmeter, and at least one medium parameter ({dot over (m)}) is calculated with the aid of the oscillation measuring variable (Δt) by means of a calculation rule representing a mathematic relation between the oscillation measuring variable (Δt), the medium parameter ({dot over (m)}) and the eigenfrequencies (f, f) of the oscillations of the measuring tube in the first natural mode and the second natural mode, and the medium parameter ({dot over (m)}) being determined taking into consideration the current determined eigenfrequencies (f, f) of the oscillations of the measuring tub in the first natural mode and the second natural mode as well as the oscillation measuring variable (Δt).
