Viscosity Measurement
Viscosity Measurement
Viscosity is a measure of a fluid’s resistance to flow. Fluids have different rheological characteristics that can be described by viscometer measurements. We can then work with these fluids to suit the lab or process conditions.
Our lab can perform viscosity measurements at defined temperatures.
We use the Brookfield DV-I+ Viscometer connected with a circulated water bath for controlling temperature
The Brookfield DV-I+ Viscometer measures fluid viscosity at given shear rates.
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.
