Density @ Ref	✓	✓
Density at reference temperature
Mass/unit volume, corrected to a given
reference temperature
SG	✓	✓	✓
Specific gravity
The ratio of the density of a process fluid at
a given temperature to the density of water
at a given temperature. The two given
temperature conditions do not need to be
the same.
Mass Conc (Dens)	✓	✓		✓	✓
Mass concentration derived from reference
density
The percent mass of solute or of material
in suspension in the total solution, derived
from reference density
Mass Conc (SG)	✓	✓	✓	✓	✓
Mass concentration derived from specific
gravity
The percent mass of solute or of material
in suspension in the total solution, derived
from specific gravity
Volume Conc (Dens)	✓	✓		✓		✓
Volume concentration derived from

reference density

The percent volume of solute or of material in suspension in the total solution, derived from reference density
