Viscosity Measurement

Measurement of viscosity using a viscometer

Viscosity is a metric for a fluid’s flow resistance. Viscometer measurements can be used to characterize fluids’ various rheological properties. Then, we can manipulate these fluids to fit the requirements of the labor process.

Viscosity measurements can be made in our lab at specific temperatures.

To regulate temperature, we attach the Brookfield DV-I+ Viscometer to a circulating water bath. The viscosity of a fluid is measured with the Brookfield DV-I+ Viscometer at specific shear rates.

The DV-I+ drives a spindle through a calibrated spring while submerging in the test fluid. The spring deflection calculates the fluid’s viscous drag against the spindle. A rotating transducer monitors spring deflection. The spindle’s size, shape, rotational speed, the container it is rotating in, and the full-scale torque of the calibrated spring all affect the measurement range of a DV-I+ (in centipoise or milliPascal seconds).
