Tag: viscometer

Viscometer is an instrument used to measure the viscosity of a fluid ( liquid or gas ). Viscosity is the physical quantity of internal friction occurring in the fluid when the fluid is flowing. It is the ability of the fluid to resist deformation and an important index used to identify some finished or semi-finished products. Viscosity varies with the type and temperature of the fluid. And what are the different types of viscometer? The following are seven common types which are widely used in petrochemical, pharmaceutical, food, light industry, textiles and other fields.

In industrial production and scientific research, the measurement of viscosity is often used to monitor the composition or quality of substances. For example, in the production of polymer materials, the application of a viscometer can monitor the viscosity of synthetic reaction products, automatic control of the reaction end point. The viscosity measurement is also required in other processes such as oil cracking, lubricating oil blending, automatic control of certain food and drug production processes, monitoring of crude oil pipelines, and quality testing of petroleum products and paints.
