This value is also used in line density measurement. Be sure that the value is
appropriate for both process variables.
4. Set Base Temperature to the temperature value to which density measurements will
be corrected (the reference temperature).
The default is 20 °C. The range is −50 °C to +200 °C.
This value is also used in line density measurement. Be sure that the value is
appropriate for both process variables.
5. (Relative density meters only) Set Density of Air to the value to be used in your
application.
Enter the value in the configured measurement unit. The default is
0.000122305 g/cm³. The range is 0.0001 g/cm³ to 0.00015 g/cm³.
