Viscosity test cup

An efflux test cup for performing high-viscosity fluid measurements to preset a process controller and validate its operation is being introduced by Norcross.

The cup is designed for manually measuring the viscosity of hotter, thicker fluids more effectively than conventional zahn or shell cups.

Featuring internal timing pins, a user dips the cup into any fluid up to 50,000 MPa, regardless of temperature and measures the time it takes for the fluid to drain from pin to pin, rather than from the bottom.

Measuring laminar flow instead of the turbulent or transitional flow out the bottom, the cup is available with several different hole sizes to handle various viscosity ranges.

Suitable for use with hot fluids, it is made of brass and stainless steel and has a brass chain to permit measurements in awkward positions under pipes and equipment.
