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.
