Abstract: A mass flow determination apparatus according to the Coriolis principle, particularly suitable as a component of an automatic dosing apparatus to obtain a highly precise measured value formation. The measuring pipe is vibration-decoupled from the process piping to prevent the internal vibration of the measuring pipe required for the measurement according to the Coriolis principle from passing into the process piping, as well as those which specifically prevent the penetration of external vibrations from the process piping into the measuring pipe.
