A viscometer is an instrument used to measure the viscosity of a fluid. Viscometers can only measure constant viscosity, that is, viscosity that does not change with flow conditions. For liquids with

The Ford viscosity cup is a simple gravity device that permits the timed flow of a known volume of liquid passing through an orifice located at the bottom. Under ideal conditions, this rate of flow wo

…a known volume of liquid to flow from the base of a cone through a short tube. This is similar in principle to the flow cups (efflux cups) like the Ford, Zahn and Shell cups which use different shapes to the cone and various nozzle sizes. The measurements can be done according to ISO 2431, ASTM D1200…
