Abstract

The invention relates to a method for determining rheological parameters of a free-flowing fluid, especially a suspension or an emulsion, which is transported by a line, especially a pipe. The inventive method uses ultrasound Doppler methods and at least two pressure measurements to obtain information relating to the free-flowing fluid. According to the invention, said information is evaluated by determining the wall shear stress in the fluid along the flow direction of the fluid flow in the region of the fluid flow penetrated by the ultrasound waves, by determining the fluid velocity profile transversally to the flow direction of the fluid flow in the region of the fluid flow penetrated by the ultrasound waves, and by selecting and adapting a suitable (adaptable) model for the viscosity function (shear viscosity) and suitable marginal conditions for the free-flowing fluid.
