The Brookfield DV-I+ 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 DV-I+.
The principle of operation of the DV-I+ is to drive a spindle (which is immersed in the test fluid) through a calibrated spring. The viscous drag of the fluid against the spindle is measured by the spring deflection.
Spring deflection is measured with a rotary transducer.
The measurement range of a DV-I+ (in centipoise or milliPascal seconds) is determined by the rotational speed of the spindle, the size and shape of the spindle, the container the spindle is rotating in, and the full scale torque of the calibrated spring.
There are four basic spring torque series offered by Brookfield:
