Flow-Cup Viscometer

Flow-Cup Viscometer

Flow-cup is used to measure liquids quickly and easily in order to determine their viscosity.


A flow-cup viscometer is a device used to measure the viscosity of liquids. It consists of a cup-shaped container with a small opening at the bottom, and a handle attached to the side for holding the cup. The liquid to be measured is poured into the cup and allowed to flow out through the small opening. The time it takes for the liquid to flow out is measured using a stopwatch, and this time is used to calculate the viscosity of the liquid.

Flow-cup viscometers are commonly used in industry and research settings to measure the viscosity of paints, varnishes, and other liquids used in coatings and surface treatments. They are also used in automotive and aviation industries to measure the viscosity of fuels, oils, and hydraulic fluids.

There are several different types of flow-cup viscometers, each designed to measure the viscosity of different types of liquids. Some examples include the Ford cup, Zahn cup, and ISO cup. The choice of viscometer depends on the type of liquid being measured and the desired level of precision.
