Capillary Viscometer

Manufacturer: Vinci Technologies
Model Number: CV

The CAVIS high-pressure capillary viscometer is specifically designed to measure the viscosity of single-phase reservoir fluids. It operates on the principle that any fluid displaced in laminar flow through a capillary tube of known dimensions, exerts a pressure drop across the tube, which is related to the flow rate of the fluid passing through it. The relationship is a function of the fluid viscosity. The computer controlled instrument consists of a high pressure opposed pump, two high accurate pressure transducers, a uniform temperature air bath and a capillary tube with consistent geometry. A set of four capillary tubes with different geometries are provided to cover the whole range of viscosity to measure.
