E.2 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.
Derived variable Description
Density Mass/unit volume,
at Reference corrected to a given
reference temperature
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.
Note
The two given
temperature conditions
do not need to be the
same.
Mass The percent mass of
Concentration solute or of material in
(Density) suspension in the total
solution, derived from
reference density
Mass The percent mass of
Concentration solute or of material in
(Specific Gravity) suspension in the total
solution, derived from
specific gravity
Volume The percent volume of
Concentration solute or of material in
(Density) suspension in the total
solution, derived from
reference density
Volume The percent volume of
Concentration solute or of material in
(Specific Gravity) suspension in the total
solution, derived from
specific gravity
