  • Page 5: Introduction

    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.

    Please check to be sure that you have received all components, and that there is no damage. If you are missing any parts, please notify Brookfield Engineering or your local Brookfield agent immediately. Any shipping damage must be reported to the carrier.
  • Page 7: Set-Up

    The Viscometer must be returned to Brookfield Engineering Laboratories, Inc. or the Brookfield dealer from whom it was purchased for no charge warranty evaluation service. Prior to the return of the viscometer, you must call for a return authorization number.

    (rpm). If you set a viscometer at a constant speed, recording cP values over time and find that the cP values decrease with time, the material is thixotropic.

  • Page 17 Brookfield publication, “More Solutions to Sticky Problems”, includes a more detailed discussion of rheological properties and non-Newtonian behavior. Viscometer Related Variables Most fluid viscosities are found to be non-Newtonian. They are Shear Rate dependent on the measurement conditions. The specifications of the viscometer spindle and chamber geometry will affect the viscosity readings.

    Brookfield Engineering Laboratories or your local Brookfield agent. Viscosity standards are Newtonian, and therefore, have the same viscosity regardless of spindle speed (or shear rate). Viscosity standards, calibrated at 25°C, are shown in Table C-1.

  • Page 19 Brookfield Viscosity Standard Fluid General Information We recommend that Brookfield Viscosity Standard Fluids be replaced on an annual basis, one year from date of initial use. Exposure to outside contaminants, such as solvent, standard of different viscosity or other foreign material, requires replacement annually. Oil Fluids do have an expiration date on the label that should be adhered to.
