Viscometer

Description:A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Viscometers only measure under one flow condition.
In general, either the fluid remains stationary and an object moves through it, or the object is stationary and the fluid moves past it. The drag caused by relative motion of the fluid and a surface is a measure of the viscosity. The flow conditions must have a sufficiently small value of Reynolds number for there to be laminar flow.
At 20.00 degrees Celsius the dynamic viscosity (kinematic viscosity x density) of water is 1.0038 mPa·s and its kinematic viscosity (product of flow time x Factor) is 1.0022 mm2/s. These values are used for calibrating certain types of viscometers.

Types of viscometers:

1.Falling ball viscometers
2.Glass capillary viscometers
3.Tuning fork vibration viscometers
4.Rotational viscometers
5.Portable viscometers
6.Viscosity cups
7.Consistometer
8.Viscometer Accessories

A viscometer is used to measure the viscosity of a fluid under defined flow conditions. The different types of viscometry instruments have either the fluid stationary and let the object pass through the fluid or vice-versa. Hence these instruments measure the drag caused by the interaction between the fluid and the object surface.
