Rheometer Test Method

A drilling fluid viscometer or rheometer is used for obtaining fluid rheology (apparent viscosity, plastic viscosity, yield point, and gel strengths), which is a measure of the resistance of a fluid to flow. Several models are available, powered by a hand-crank or electric motor. The instrument comprises a solid pivoted cylindrical bob that is restrained by a torsion spring and connected to a torsion dial.
