Apparatus and method for detecting vibrations, e.g. in a coriolis mass-flowmeter, using noise filtering

Wherein a estimation of with in the structure (3) are related process parameters. A receiving represents a vibration structure multiple position (5A-5D) multiple motion of power of (605). Motion force of filter signal according to multiple of power for receiving the forcibly filter (610) (605) arranged on the force filter is provided with a identifying to the force and a to multiple force in the structure of the function (615). Predictive approximation of the force of filter signal with a on the vibration structure (3) are related process parameters (625).
