Abstract:
1. A method for correcting a measurement signal by compensating for influences, which interfere with accuracy of the measurement signal, in measurement devices of the vibration type, comprising a measurement tube through which a fluid medium can flow and which is caused to oscillate mechanically, acting as an oscillation body, by an excitation unit, whose oscillation behavior, which changes as a function of flowrate, viscosity or density of the fluid medium, is detected by at least one oscillation sensor in order to determine the flowrate, the viscosity or the density of the fluid medium, wherein an indicator value for an influence causing a material strain in the measurement tube is calculated from the material strain in circumferential direction of the measurement tube by means of at least one sensor, in order to correct the measurement signal, using signal processing, from the indicator value by compensating for inaccuracy of the measurement signal caused by the influence.
