Ultra High Pressure Viscometer: UHPV-100

A new Instrument for the Accurate Determination of the Viscous Properties of Newtonian and Non-Newtonian Fluids at Ultra High Pressures.

The Ultra High Pressure Viscometer (UHPV-100) consists of a metal needle with hemispherical ends falling vertically in a fluid with its longitudinal axis along the axis of a cylindrical container. A measurement of the needle terminal velocity allows a determination of the viscous properties of the test fluid. With the UHPV-100 the needle falling time is measured automatically by means of Hall sensors and a magnet in the needle.
