Abstract
A Coriolis-type mass flow meter is disclosed which can be installed, e.g., via flanges, in a conduit of a given diameter so as to be axially aligned with said conduit, which is traversed by a fluid to be measured. To further improve and optimize its insensitivity to vibrations originating from the conduit, this Coriolis-type mass flow meter comprises: at least one measuring tube fixed to the flanges; a support tube having its ends fixed to the respective flanges; means for exciting the measuring tube into resonance vibrations; velocity sensors positioned along the measuring tube for sensing the vibrations of the measuring tube; acceleration sensors positioned on the support tube along a line of intersection with that plane in which Coriolis forces act; and means which process signals from the velocity sensors and signals from the acceleration sensors into a mass flow signal which is substantially free from interference.
