ABSTRACT:
Method for the dynamic and density-independent determination of the mass flow of fluids. A single vortex generating bluff body is placed in the flow to generate vortices according to the principle of the Karman vortex path. The dynamic pressure (1/2.rho.v.sup.2) is determined via the effect of the drag directly at this bluff body. The velocity of flow (v) is determined via the effect of the vortex shedding at the bluff body. The mass flow is determined according to the equation:
