A common rotational viscometer is a cone-plate viscometer. It mainly consists of a plate and a cone plate. The motor drives the plate to rotate at a constant speed through a change gear, and the measured sample is kept between the two plates by capillary action, and the cone plate is driven to rotate by the friction force between the molecules of the sample.

If you wish to study viscosity in rotation, Anton Paar’s ViscoQC 100/300 and RheolabQC achieve precisely what is required, no matter whether you want to run quick single-point viscosity checks or simple rheological tests. Rotational Viscometer / Rotary Viscometers 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 … 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.

1.1 These test methods cover the use of rotational viscometers to determine the dependence of apparent viscosity of paints, inks and related liquid materials on

Calibration with Newtonian substances indicates rotational viscometer, which has been solved by Krieger and co-workers for various sets of boundary conditions [Krieger and Maron, 1952]: D 1 2 Z R c R b f.˝/ ˝ d˝.2:10/ where is the angular velocity of the spindle with respect to the cup, ˝is the shear stress in the ﬂuid at any point in the system, f.˝/DP is the rate Operation Procedure for Viscometer: Ensure that equipment is clean. Check the level of instrument with the help of spirit level on the top of the Viscometer, and if required set level with help of three screw on triangle bottom.

They measure viscosity by sensing the torque required to rotate a spindle at constant speed while immersed in fluid. The torque is proportional to the viscous drag on the spindle; thus the sample viscosity.
