Rotational viscometers are used to measure viscosity. Myr Viscometers V1 and V2 are classic rotational viscometers for the fast determination of viscosity according to following standards: BS: 6075, 5350 ISO: 2555, 1652 ASTM: 115, 789, 1076, 1084, 1286, 1417, 1439, 1638, 1824, 2196, 2336, 2364, 2393, 2556, 2669, 2849, 2983, 2994, 3232, 3236, 3716 This precision Rotational Viscometer is user-friendly and easy to program, simply select a Spindle and the preferred Rotation Speed and with the touch of a softtouch button the viscosity values in cP and in mPa·s of your samples are presented on the large LCD display with backlight comfortable to read under different light conditions. Rotational viscometers are much more expensive but, at the cheaper end of the range, the Brookfield viscometer is extremely useful and popular. As the viscometer became more sophisticated, it became possible to program them, and to take a fluid through a shear stress–shear rate cycle, to increase or decrease the shear rate at fixed rates or to hold at a constant shear rate for a fixed time. Description. Apparent viscosity of unfilled asphalt is evaluated by a rotational viscometer which measures the torque generated by a calibrated spindle rotating at a selected speed into a bitumen sample heated at precise temperature in the range between ambient temperature to 260° C. Most commercial rotational viscometers incorporate this principle, which is named after G.F.C. Searle (George Frederick Charles Searle, 1864 – 1954, a British physicist and teacher, who designed a rotational viscometer with rotating concentric inner cylinder in 1912).

Figure 2.2.10.-5 Figure 2.2.10.-6 In a general way, the constantk of the apparatus may be determined at various speeds of rotation using a certified viscometer calibration liquid. The viscosityηthen corresponds to the formula: METHOD Measure the … In Rotational Viscometers the liquid (1) whose viscosity is to be measured fills the space between two vertical coaxial cylinders (cup and bob) or between a cone and a plate. There are two classical geometries in cup and bob viscometers: Rotational Viscometer, advanced models.
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: Spring-type instruments; Servo motor instruments
The viscometer requires no further calibration once it is set. 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.

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 made over time, allowing time-dependent fluid analysis.
