In gefaehrlicher Umgebung arbeitendes abgedichtetes Viskosimeter

摘要

A viscosimeter for measuring the viscosity of fluids or suspensions especially those which may be inherently dangerous such as radioactive fluids. The fluid is placed in a sealed casing with a cylindrical body inside. The casing is resiliently suspended for axial oscillation in a sheath which can be evacuated. Means such as a solenoid are provided to oscillate the casing. Means outside the sealed area to measure the damping of the oscillations of the cylindrical body are also provided.
