Abstract
A method for operating a resonance measuring system, in particular a Coriolis mass flowmeter, an oscillation element is excited to oscillation and the oscillations of the oscillation element are detected by an oscillation sensor and are formed as at least one response signal of a respective eigenform. Orthogonal projection components of the response signal are created, at least a first value corresponding to an eigenfrequency of the resonance measuring system is determined with at least a part of the alternating components of the projection components, at least a second value corresponding to the eigenfrequency of the resonance measuring system is determined with at least a part of the constant components of the projection components and the first and the second value correspondents are used for exciting the resonance measuring system with at least one control in at least one control loop in the eigenform corresponding to the eigenfrequency.
