SUMMIT 8800 STREAM CONFIGURATION 06
Figure 103 Line density table
The contents of the table can be imported from another configuration by clicking on the button
“Import” and selecting the other configuration.
6 .8 .7 TAB calculated (liquid only)
If selected, the pressure and temperature at the density point must be specified in the TAB
“calculated”. The SUMMIT 8800 uses the Klosek-McKinley equation to calculate density for LPG
or LNG.
Figure 104 Liquid line density calculation method
This section requires the user to enter the molecular weight source. Three options are available:
Keypad A fixed value to be entered
ISO 6976:1995 Using the ISO formula
GPA 2172:1996 Using the GPA formula
Furthermore the pressure and temperature at the density point must be specified. Their selec-
tion is almost identical to the stream pressure and temperature selection. Please note that in
this case only 2 pressure and temperature sensors are possible but that also the pressure and
temperature at the meter can be used.
6 .8 .8 TAB Z-equation (gas only)
If “calculated using AGA8 or PTZ” was selected, the equation for Z-factor compressibility used
must be specified in the TAB “Z-equation”:
