Zahn Viscosity Flow Cups

A preset volume of fluid draining through a set hole size.

Zahn viscosity flow cups.

To determine viscosity dip the cup in a liquid until it is completely filled lift the cup out of the liquid and time how many seconds it takes for the liquid to drain out of the hole in the bottom. Five sizes are available for use on very thin oils to extremely heavy mixtures 20 1200 centipoise. The zahn cup s reading could be less sensitive than an automated viscometer employing a higher shear methodology. The size of the hole is in mm and a zahn 4 means a zahn cup with a 4mm hole.

The ez viscosity cup series is a logical and necessary outgrowth of the standardization studies on the zahn signature and similar cups for the promotion of this most popular type of viscosity measuring instrument as a national and international standard.

Different cups have different shapes and hole sizes and because times too short or too long are unsuitable for any given viscosity there is an optimum cup with times in the 15 60s range.
