The Brookfield Dial Viscometer measures fluid viscosity at given shear rates. Viscosity is a measure of a fluid s resistance to flow. You will find a detailed description of the mathematics of viscosity in the Brookfield publication More Solutions to Sticky Problems a copy of which was included with your Dial Viscometer. The Dial viscometer rotates a sensing element in a fluid and measures the torque necessary to overcome the viscous resistance to the induced movement. This is accomplished by driving the immersed element, which is called a spindle, through a beryllium copper spring. The degree to which the spring is wound, indicated by the red pointer, is proportional to the viscosity of the fluid.
The Viscometer is able to measure over a number of ranges since, for a given spring deflection, the actual viscosity is proportional to the spindle speed and is related to the spindle's size and shape. For a material of given viscosity, the resistance will be greater as the spindle size and/or rotational speed increase. The minimum viscosity range is obtained by using the largest spindle at the highest speed; the maximum range by using the smallest spindle at the slowest speed.
There are four basic spring torque series offered by Brookfield:
Model Spring Torque (Dyne-cm)
The higher the torque calibration, the higher the measurement range. The viscosity measurement range for each torque calibration may be found in Appendix B.
All units of measurement are calculated in units of centipoise (cP) by using a look-up table known as "the Brookfield Factor Finder" to convert torque reading.
The equivalent units of measurement in the SI system are calculated using the following conversions:
* Viscosity: 1 cP = 1 mPa s mPa s = milli Pascal - second
* Torque: 107 dyne-cm = 1 Newton-m
