    Abstract: The invention relates to a multi-sensor mounting system (10), which comprises a secondary pipe (100) and an adapter (210), for detecting or monitoring a characteristic or a plurality of characteristics of a fluid in a process pipe (20). The secondary pipe (100) comprises a fastening device (110), configured to fix the secondary pipe (100) to the process pipe (20), and a valve (120), configured to be switchable between an open state and a closed state. The adapter (210) is configured to connect a sensor module (200) to the secondary pipe (100) in a detachable manner. The valve (120) is configured to allow a sensing probe (201) of the sensor module (200) being inserted into the process pipe (20) in the open state, and to block a fluid flow in the secondary pipe (100) in the closed state, when the sensing probe (201) is removed from the secondary pipe (100).

The method comprises the steps of: Selecting the section (14) of the pipe-fluid system (10), the section (14) being delimited by a pair of stiff delimiters (11, 19);
    performing a numerical vibration simulation of the section (14) of the pipe (20), resulting in a computed Eigen-frequency range (ftarget) of computed maxima of the pipe-fluid system (10);
    inducing, by an excitation means (40), a first vibration of the section (14);
    acquiring, by at least two vibration measurement devices (50), a set of first maxima (M3a, M4a, M5a) in an amplitude-frequency diagram (80), with a first frequency (f3a, f4a, f5a) within the computed Eigen-frequency range (ftarget);
    selecting, by means of a vibration mode analysis, a first hoop mode maximum (M3a) out of the set of first maxima (M3a, M4a, M5a);
    inducing, by the excitation means (40), a second vibration of the section (14); acquiring, by the at least two vibration measurement devices (50), a set of second maxima (M3b, M4b, M5b) in the amplitude-frequency diagram (80), with a second frequency (f3b, f4b, f5b) within the computed Eigen-frequency range (ftarget);

    Abstract: The present invention relates to a method for non-invasive measurement of physical parameters of fluids in process pipes (4).
