ABSTRACT:
A method of measuring the flow properties of preferably high viscosity fluids, where a fluid is applied to a gap between a rod and a ring and subjected to a shear force by the mutual displacement of the ring and the rod, and where either the rod or the ring is imparted a controlled movement relative to the ring or the rod, respectively. Furthermore a device for carrying out the inventive method is provided. The device is of a size suitable for laboratory use and enables an improved temperature control as well as the determination of a complete flow curve in a single experiment.
