<p>The invention relates to a measuring sensor (10) that generates a measuring signal that corresponds to at least one physical parameter of a fluid flowing through a pipeline. For this purpose, the measuring sensor (10) comprises at least one measuring pipe (13) having a determined measuring pipe volume for guiding the fluid, whereby said measuring pipe (13) communicates with the pipeline at the inlet and outlet side. An inducer arrangement (16) brings about, when operated, reactions in the fluid inside the at least one measuring pipe (13). These reactions can be reactive forces and are detected in a non-invasive manner by a sensor arrangement (60) and are converted to measuring signals that represent the reactions in the fluid. In order to produce as rotation-symmetrical a density distribution in the fluid as possible, means are provided in an inlet zone of the measuring sensor (10) or at least in the vicinity thereof that effect, in the fluid flowing inside the measuring pipe volume, a swirl in the inflowing fluid and thus a rotational movement about an imaginary rotational axis that lies in the direction of flow relative the measuring pipe (13). Due to the rotation-symmetrical density distribution so obtained, the measuring sensor (10) is capable of supplying exact and robust measuring signals even in inhomogeneous, especially multi-phase fluids, especially substantially irrespective of the assembly position of the measuring pipe (13).</p> |
