7.4.11 DI Adjustable extra base condition
Figure 217: Menu DI Adjustable extra base condition
Usually, the base conditions in German-speaking countries are based on 0° C and
1,013.25 mbar. Different bases of standardization in other countries can require dif-
ferent reference values; they can be entered in this menu. As a result, different flow
rates and density values at base conditions arise.
This is important for systems at national boundaries. With "different" pressure and
temperature reference values to be entered in
DI11
and
DI12
, correct conversion to
the various base values can take place.
The variables of flow rate Qb, density at base condition and ratio of two densities at
different base conditions, sd (extra base condition) / sd (base condition) are convert-
ed with reference to other base conditions. These values are available for assign-
ment to the current outputs.
7.4.12 DL Calculations according to GPA 2172-96
Figure 218: Menu DL Calculations according to GPA 2172-96
GPA 2172-96 is an American regulation for calculation of calorific value, heating val-
ue, real gas factor and density ratio; it is used instead of ISO6976. This regulation is
used in the USA and parts of the far east.
