About Viscometers

Viscometers are precise instruments used to measure the viscosity (resistance of a fluid against shear or tensile stress) and flow of a fluid. However, it is worth noting that viscometers can only measure under one flow condition (ie. shear OR tensile). They are most commonly used in the quality control (QC) industry, where both Viscometers and Rheometers (a type of viscometer for measuring fluids with a higher viscosity – sometimes also known as plastometers) are used to measure anything from the viscosity of a new medicine to the viscosity of paint.

Tapes of Viscometers

Ubbelohde Viscometer

Also know as glass viscometers (or glass capillary viscometers), U-Tube viscometers are made up of a U-shaped glass tube that is held vertically in a temperature controlled bath. A similar viscometer is the ‘Falling Sphere Viscometer’, which is similar to the U-Tube version, but based around Stokes’ Law.

Rotational Viscometers

The popular rotational viscometer, uses the mechanical force of the torque required to turn an object in the fluid. There are two main types of the rotational viscometer, the ‘Cup and Bob’ and the ‘Cone and Plate’.

Vibrational Viscometers

Based on the Bendix instrument of the early 1950’s, the ‘Vibrational Viscometer’ operates by measuring the damping of an oscillating electromechanical resonator immersed in a fluid.

Viscometer Calibration and Servicing

It is very important with viscometers to make sure they are calibrated correctly in order to achieve accurate results. Similarly with servicing, it is important to make sure your viscometer is regularly serviced, to maintain these accurate results. For more information of services and calibration, see the links below:

QC labs also offer calibration and servicing on all viscometers. For more information, please get in touch.
