This paper presents the concept of a novel capillary viscometer for high pressure applications and high shear rates. First, the general procedure for a viscosity measurement with a capillary is described. Subsequently, the practical implementation of this measuring principle in the viscometer, which is currently used at the Institute for Fluid Power Drives and Systems (ifas) for viscosity measurements and was also developed there, will be shown. Measurement results and conceptual challenges will be discussed. Based on this, the new concept is described with its advantages over the current viscometer.
