摘要： The disclosure relates to a vibration-type measuring device for measuring at least one process variable, in particular a mass flow rate, a density, a viscosity, a pressure or the like, in particular in a process line through which a medium can flow, which device comprises at least one measurement sensor which provides a measurement signal that can be influenced by the process variable, the measured value determined for the process variable by the measuring device being able to be determined from a functional relationship in conjunction with measurement parameters from the measurement signal, and the measurement parameters having a temperature-dependent cross-sensitivity with respect to the temperature distribution in the measuring device. The measuring device comprises at least one temperature sensor, by means of which the local temperature can be measured, and a temperature distribution field can then be calculated with electronic means using a temperature distribution theorem, and correction values for compensating for the temperature-dependent cross-sensitivities of the measurement parameters can be determined from the temperature field data.

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.

Furthermore, stabilizing elements running parallel to the measuring tube are coupled to the measuring tube via mounted parts connected directly to the measuring tube, the mounted parts and the stabilizing elements consisting of a metal other than that of the measuring tube. The stabilizing elements are manufactured from a second material which possesses a coefficient of thermal expansion adapted to the metal of the measuring tube. The mounted parts connected directly to the measuring tube are manufactured from a third material which possesses a higher coefficient of thermal expansion than the metal of the measuring tube.
