E.3 Derived variables and calculated process
variables
The concentration measurement application calculates a different set of process variables
from each derived variable. The process variables are then available for viewing or
reporting.

✓ ✓
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 temper-
ature conditions do not
need to be the same.
✓ ✓ ✓
Mass Concentration
(Density)
The percent mass of
solute or of material in
suspension in the total
solution, derived from
reference density
