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
