Overview
The base density parameters provide data for the base density calculations. Base density
can be reported as a process variable. For specific gravity meters and relative density
meters, base density is required for line density measurement.

Device Tools > Configuration > Process Measurement > Base Density
Choose Device Tools > Configuration > Process Measurement > Base Density.
Set Density Unit to the unit to be used for base density, and click Apply.
This unit is also used for line density.
Set Base Pressure to the pressure value to which density measurements will be
corrected (the reference pressure).
The default is 1 bar absolute. There is no upper limit. You must be using absolute
pressure.
