Rotational Viscometer - an overview | ScienceDirect Topics
Rotational viscometers evaluate the fluid viscosity by measuring the torque required to turn an object in that fluid. Using this viscometer, the viscosity of both Newtonian and non-Newtonian fluids can be measured.

Rotational viscometers are perfect for determining the viscosity of a wide range of different samples. Viscosity testing with rotational viscometers is suitable for everything from liquid samples to semi-solid ones.
What is a Rotary Viscometer? Types & NDJ-8s Parameters
2022年10月18日 · What is Rotary Viscometer? The rotational viscometer measures the viscous resistance and dynamic viscosity of the liquid. The rotational viscosity measurement method pioneered by the Brookfield family in the United States uses its unique relationship between the shear and resistance generated between the rotor and the fluid to obtain a new ...
Rotating viscometers are used for measuring the viscosity of Newtonian (shear-independent viscosity) or non-Newtonian liquids (shear dependent viscosity or apparent viscosity). Rotating viscometers can be divided in 2 groups, namely absolute and relative viscometers. In absolute viscometers the flow in the measuring geometry is well defined.

Rotational viscometers are designed to measure viscosity by analyzing the torque required to rotate a spindle submerged in a fluid at a constant speed. The continuous rotation of the spindle ensures calculations are made over time, allowing time-dependent fluid analysis. Digital models can evaluate low, medium, and high viscosity materials.
How Rotational Viscometer Works and Its Role in Determining
There are several types of rotational viscometers, including coaxial cylinder viscometers, cone-and-plate viscometers, and rotating spindle viscometers. Each type of viscometer has its own advantages and limitations, and the selection of the appropriate viscometer will depend on the specific requirements of the measurement.

The rotary viscometers use the torque on a rotating shaft to measure a fluid’s resistance to flow. The shear rates can be changed by modifying the speed of rotation, rotor dimensions, and the gaps between rotor and stator.
Viscometers may be classified in four categories namely capillary viscometers, vibration viscometer, Rotational Viscometers and special purpose viscometers. Theory and details of Capillary viscometers is given in Chaps. 1 and 3; vibration viscometers have been discussed in Chap. 5. Rotational and special purpose
