Thus, the viscometer can be entirely remotely controlled and is, therefore, recommended for experimental situations which make the liquid not easily accessible, e.g. There are three types of capillary type viscometers as discussed below: o Cannon Manning Vacuums Viscometer- The range of the viscosity that this viscometer is able to measure depends on the size of the viscometer. The oscillations are stimulated electrically the positioning of the transducer core is precisely adjustable with the use of an electric motor driven mechanism. Viscometer- Capillary type: It is made up of borosilicate glass. The oscillations of the system are sensed by electrically recording the output of a linear variable differential transformer, the core of which forms a part of the oscillating system. Using five sample liquids, at room temperature, the average error between the absolute viscosities determined and those of previous measurements is ± 1.5%.The viscometer consists of a quartz spring, which suspends a solid gold sphere, hanging vertically. Cannon Manning Viscometers are designed for the determination of the absolute viscosity & Kinematic viscocity of bitumen & cut - backs by a vacuum capillary.

Accuracy: 5 full scale (FS) in Newtonian fluids. Rotational speed: 6, 12, 30, and 60 rpm.

The use of this technique for the determination of absolute viscosity of liquids is demonstrated. Thus, the PCE-RVI 1 analogue viscometer offers an affordable solution for viscosity measurement during product and material testing, development, production and quality control. The mathematical theory of a solid sphere oscillating in a viscous liquid is developed, and results in an exact equation depicting the relationship between the logarithmic decrement of the oscillations of the sphere and the viscosity of the liquid surrounding the bob. with unit speed relative to another parallel plane surface, from which it is separated by a layer of the liquid of unit thickness. A novel type of vertically oscillating bob viscometer for liquids is described.
