Cup and orifice production tolerance permits replacement or inter-change of orifices without loss of acceptable cup accuracy. The orifices for the cup are machined from stainless steel with the exact conical exterior to match the opening in the base of the cup. Positive orifice identification is assisted by "steps" at the base of the orifice as shown in the cross section drawing. See "Care of Cup" for orifice removal instructions.

Flow Cups are designed to accurately measure the viscosity  of paints, inks, varnishes and similar products. The process of flow through an orifice can often be used as a relative measurement and classification of viscosity.
This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into centistokes cSt using a viscosity calculator. From Wikipedia, the free encyclopedia.
