Abstract
The inventive method uses the ultrasound Doppler method (UVP) in order to determine a local velocity profile perpendicular to a line for a fluid which flows through said line, carrying suspended or emulsified particles. The wall shear stress of said fluid is measured locally within the range of said local velocity profile. Specific rheological parameters of the flowing fluid thus examined, e.g. viscosity function (shear viscosity), flow limit etc., can be determined from the local velocity profile and the local wall shear stress associated therewith. A suitable model is adapted by iteratively adapting a model-based theoretic velocity profile to a measured velocity profile.
