Abstract

A method including: at least one oscillation measurement signal serving as primary signal of first class representing vibrations of a measuring tube, through which medium to be measured is momentarily flowing; and at least one oscillation measurement signal serving as primary signal of second class representing vibrations of at least one measuring tube, especially of the same measuring transducer, and orbiting around the axis of rotation of a carousel-type filling machine orbiting, but not containing flowing medium. Furthermore, based on both the primary signal of first class as well as also the primary signal of second class, at least one measured value, representing a measured variable, especially a mass flow rate and/or an integrated mass flow and/or a density of medium to be measured, is generated. Additionally, an apparatus is provided suited for reducing the method to practice and/or embodied as a carousel-type filling machine.
