Rotational viscometers work by getting the measurements of the torque on a vertical stand that moves the spindle in a rotational direction. The rotation of the spindle is usually proportional to how viscous the sample is.

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.
In this set-up, the system mainly uses a spring. The spring is used to measure the torque strength on the spindle. The springs in this system are always marked and calibrated to make it easy to note and read the measurements. Usually, about three to four spring ranges exist. Of importance to note here is that, each particular range is directly related to a particular strength of viscosity.
Servo system is the second system that can be used to measure the torque. This system mostly relies on a servo motor. The precision servo motor is used to move the shaft. In this system, the spindle is usually connected directly to the shaft. This is unlike in the spring system in which the spindle is connected to the pivot.
