Abstract
A mass flowmeter employing the Coriolis principle incorporates in at least one section two measuring tubes that extend along a common plane, as well as a connecting device that connects the two measuring tubes in the section in which they extend along the common plane. The connecting device is designed and positioned in a manner whereby its flexural strength for flections in the common plane of the measuring tubes is greater than its torsional rigidity for torsional oscillations around the connecting line between the two measuring tubes. This achieves good frequency separation between the excitation oscillations generated in the common plane of the measuring tubes and the oscillations of the measuring tubes perpendicular to the former.
