Abstract
A mass flowmeter operating by the Coriolis principle and incorporating an essentially straight, moving-fluid-conducting Coriolis measuring tube, at least one oscillator associated with and exciting the Coriolis measuring tube, at least one detector associated with the Coriolis measuring tube and sensing the Coriolis forces and/or the Coriolis oscillations generated by Coriolis forces, and a compensating cylinder in which the Coriolis measuring tube is positioned, the Coriolis measuring tube and the compensating cylinder being connected to each other in which the oscillation-capable system composed of the Coriolis measuring tube and the compensating cylinder is at least to a large extent mass-equalized both for the excitation oscillation of the Coriolis measuring tube and for the Coriolis oscillation of the Coriolis measuring tube.
