A preset volume of fluid draining through a set hole size.
Zahn viscosity flow cups.
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.
The only forces at work are gravity causing the flow and the hole size and gauge of the cup.
The zahn viscosimeter is a bullet shaped corrosion resistant stainless steel cup with a precision drilled orifice.
Five sizes are available for use on very thin oils to extremely heavy mixtures 20 1200 centipoise.

Also known as zahn cups these testers let you calculate viscosity based on the speed at which a liquid drains through a cup with a hole at the bottom.
Viscosity is determined by the time required for a definite volume of liquid to flow through the orifice.
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.
