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 Rotational viscometer is widely used to measure the dynamic viscosity of various fluids such as grease, paint, coating, plastic, food, medicine, adhesive and so on. It is popular because of the simple structure, cheap price, convenience and practicality. Rotational viscometers measure the viscosity of the sample by turning a spindle in a cup. The viscosity is determined through the measurement of the torque on a vertical shaft that rotates a spindle. Two different setups are used when measuring viscosity using a rotational viscometer: By looking at other rotational viscometers: some use a synchronous motor held constant speed by the power line.

Rotational viscometers are used to measure viscosity. It is common to find most rotational viscometers looking the same, however, two unique and different set-ups are used when measuring viscosity using the rotational viscometer. Below are the two main systems that shows how a rotational viscometer work. Spring systems The rotational viscometer senses torque required to rotate a spindle at constant speed while immersed in the sample fluid. Dynamic viscosity is proportional to this measured torque. The standard RV is quite common in chemical and food industries for measuring the viscosity of non-Newtonian fluids.

In the following, you can see more products in the field of the "Analogue Rotational Viscometer": It is also known as or Rotation Viscometer or R In this Physics video lecture in Hindi we discussed about the principle and working of Rotational Viscometer. AMETEK Brookfield's line of viscometers, including laboratory viscometers, gel timer instruments, and in-line process viscometers. Used for a variety of industry applications. The world’s most successful viscometers. Anton Paar’s viscometers have revolutionized viscosity measurement.

By looking at other rotational viscometers: some use a synchronous motor held constant speed by the power line. The solution container wants to turn. A simple coil spring keeps the container from turning too far. Watching how far the spring turns.
