    摘要: A vibration-type measuring device includes an exciter arrangement which exerts a time-dependent force with at least one sinusoidal component at an adjustable excitation frequency on a measuring tube, through which a medium can flow, and causes the measuring tube to oscillate. The measuring device includes first and second sensors which are fitted to the measuring tube at different locations. The first and second sensors output first and second measurement signals, respectively. The measuring device includes an evaluation unit which determines a first phase shift between the first and second measurement signals and uses the determined phase shift to determine a measurement variable of the medium. The measuring device includes a phase comparator, which determines a second phase shift between the force and the average value of the first and second measurement signals, and a frequency generator which sets the excitation frequency on the basis of the second phase shift.

    摘要: 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.
