    • A coriolis mass flow pick-up is disclosed, which can be inserted into a pipeline and has a fluid to be measured flowing through it during operation. The pick-up includes a single measuring pipe, which has an inlet end and an outlet end, an exciter arrangement, which causes the measuring pipe to carry out at least first bending oscillations, and at least two sensors for sensing movement of the measuring pipe. At least two elongate connection parts, which extend freely essentially parallel to the measuring pipe and whose central axes are displaced from the axis of the measuring pipe, are connected on the input side and the output side to the measuring pipe. The connection parts carry out second bending oscillations in the event of an oscillating measuring pipe, with the result that, by the second bending oscillations of the connection parts being superimposed by the oscillations of the measuring pipe, bending forces and torsional moments at the inlet and outlet ends of the measuring pipe are compensated.
    • 公开了科里奥利质量流量拾取器,其可以在操作期间插入到管道中并且具有待测量的流体流过它。 拾取器包括单个测量管,其具有入口端和出口端,激励器布置,其使得测量管至少执行第一弯曲振动;以及至少两个传感器,用于感测测量管的运动 。 至少两个细长的连接部件,其基本上平行于测量管延伸,并且其中心轴线从测量管的轴线移动,在输入侧和输出侧连接到测量管。 在振荡测量管的情况下,连接部分进行第二弯曲振荡,结果是,连接部分的第二弯曲振动由测量管的振荡叠加,入口处的弯曲力和扭转力矩以及 测量管的出口端被补偿。
