Copper-Metal Flow Cup

The copper flow cup determines viscosity by measuring the time it takes for a fluid to flow out from a small hole at the bottom. It is used for on-site rapid testing in industries such as coatings and inks, offering simple operation and portability.
Selection
When selecting a copper flow cup, it is essential to consider matching the viscosity range of the material being tested with the cup’s designated number. Priority should be given to standard orifice models to ensure data comparability. Additionally, the cup’s orifice should be free of burrs and come with temperature correction instructions.
