How should the concentration of solids be expressed?

For slurry applications, how should concentration of solids in the liquid stream be expressed?
Slurry solids concentration may be expressed in several ways. For modeling and other scientific studies, concentration by volume is most often used, since it relates most directly to the underlying physical mechanisms.
However, within a given industry or field, slurry concentrations are often expressed in terms of the concentration by weight, which represents the most direct form of measurement.
Specific gravity of the slurry mixture is often used since it simplifies pump and pipeline calculations.
For more information on slurry solids, refer to ANSI/HI standard 12.1-12.6 Rotodynamic Centrifugal Slurry Pumps at www.pumps.org/standards.
