    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 process is disclosed for operating a measurement device of the vibration type in which at least one exciter arrangement excites the system to vibration and from the vibration parameters, a measurement quantity of a measurement medium in a tube system is determined. A time-dependent force f(t)=F sin(ωt)+g(t) with at least one sinusoidal component with an adjustable frequency ω can be used which acts on at least one vibration-capable part of the measurement device of the vibration type. A response signal of the vibration-capable part, (e.g., its time dependent velocity v(t)=V sin(ωt+ψ)+h(t)) can be measured, and a phase shift Ψ between the response signal and the force f of a signal component which oscillates with a frequency ω is determined. The phase shift Ψ can be used as the input for a frequency controller so that the excitation frequency is automatically adjusted as a function of Ψ.
