摘要： A device for measuring the mass rate of flow according to the Coriolis principle, with two measurement tubes at least in one section of which runs in a common plane, and a connector by which the two measurement tubes are connected to one another where they run in a common plane. The connector has a stiffening plate which is parallel to the common plane of the measurement tubes and which is attached to the two measurement tubes. At least one stiffening fin is provided on the stiffening plate so that the bending stiffness of the connector for bending in the common plane of the measurement tubes in which, generally, excitation vibrations of the measurement tubes also take place, is made greater than the torsional stiffness of the connector for torsional vibrations. As a result, the measurement accuracy of the Coriolis mass flow rate measurement device is improved.

摘要： 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.
