Abstract: A measuring arrangement for determining flow velocity of at least one liquid phase and/or a gas phase of a vapor or a fluid composed of a liquid and a gaseous phase or a supercritical fluid, comprising a measuring tube, on or in which at least one sensor element of at least a first flow measuring device is arranged for measuring the liquid phase or the gas phase, wherein the measuring tube has at least an inflow region and an outflow region, wherein between these two regions a central region is arranged, whose measuring tube cross section has a greater area than the area of the measuring tube cross section of the outflow region or of the inflow region, and method for ascertaining flow of phases of a vapor or of a fluid composed of a liquid and a gaseous phase, or a supercritical fluid.

Abstract: Disclosed is a tube configured to conduct a fluid flowing through the tube in a specified flow direction and for this purpose comprises a tube wall, which encloses a lumen of the tube, and an interference body, which is arranged within the tube but is nevertheless connected to the tube wall at an inner face of the tube wall facing the lumen. In the tube according to the present disclosure, the tube wall has a maximum wall thickness of more than 1 mm and at least two mutually spaced sub-segments with a respective wall thickness that deviates from said maximum wall thickness, wherein the sub-segment is positioned upstream of the interference body in the flow direction, and the sub-segment is positioned downstream of the sub-segment in the flow direction.

Abstract: A magneto-inductive flow measuring device comprising a measuring tube on which a magnet system and two or more measuring electrodes are arranged and/or secured. The measuring tube has in- and outlet regions with a first cross section and the measuring tube has between the in- and outlet regions a middle segment, which has a second cross section. The measuring electrodes are arranged in the middle segment of the measuring tube and the middle segment at least in the region of the measuring electrodes is surrounded by a tube holder, which guards against cross-sectional deformation of the second cross section.
