    摘要: A system and method for non-invasive measurement of physical parameters of fluids in process pipes includes exciting the process pipe, measuring a vibration signal, and reducing the frequency range of the measured vibration signal to a range where a predicted resonant frequency is located. The method further comprises estimating the number of parameters and values for the parameters for a fitting algorithm, fitting the fitting algorithm to the processed measured vibration signal, and adapting the parameters so that the curve of the fitting algorithm fits to a curve of the processed measured vibration signal. The physical parameter is determined from the parameters.

    摘要: A system and method for determining a physical parameter of a fluid in a pipe includes performing a numerical vibration simulation of the section of the pipe resulting in a computed Eigen-frequency range of computed maxima; inducing a first vibration and acquiring first maxima in an amplitude-frequency diagram; selecting a first hoop mode maximum and inducing a second vibration to acquire second maxima with a second frequency. Using a vibration mode analysis, a second hoop mode maximum is selected and the physical parameter of the fluid is derived from a difference between the first hoop mode maximum and the second hoop mode maximum.
