Configure AGA3 Process Parameters
If you choose the AGA3 gas flow calculation standard, you need to configure
these parameters:
• Instrument parameters
• Orifice Plate parameters
Instrument Parameters for AGA3 Standard
• Base Pressure and Base Temperature
This is the pressure and temperature under base conditions.
• Pressure Type
This is the static pressure type tested by pressure meter. The pressure
type could be an absolute static pressure or gauge static pressure.
If it is the absolute static pressure, then entering the atmospheric
pressure is not required.
Absolute static pressure = Gauge static pressure + Atmospheric
pressure

For any changes to parameter settings to be applied to the
DataSite controller, you need to click Download.
IMPORTANT
Before downloading any changes to the DataSite controller,
it is recommended that you perform an upload. This helps
prevent modifying information that you did not intend to
