3.6.2 Density Units
You may change the density units displayed on the Main Screen to any of the following:
gm/cc
kg/cuM
lb/cuft
lb/gal
SGU
Ref@15C
Select the density units you desire from the drop down box. Please be aware that the density on the
Main Screen will be displayed in the units you select but the 4-20mA density output and density alarm
levels and density units used in calculating the result remain set in gm/cc. Access is allowed for
Operator2 (Level 2) or higher password.
The option for reference density shows the calculated density in gm/cc based on the theoretical
contraction or expansion of the sample from the measured temperature of the flow cell to a base
temperature of 15.5° C. The reported reference density is for information only and is not appropriate
for fiscal calculations. Differences between the measured flow cell temperature and the actual sample
temperature and differences between the theoretical expansion coefficient and the actual sample
response may make the reported reference density inaccurate.
