5.10.2 Configure AGA8 parameters
Configure the properties necessary for the AGA8 calculations.
How the AGA8 calculations to be performed:
• Internally by the meter - calculates the flow mass density, the flow compressibility
and the base compressibility.
• Externally - calculations are done externally. The calculated values must then be
written to the meter using Daniel MeterLink
™
or a flow computer.
AGA8 method
• Gross Method 1
• Gross Method 2
• Detail - enter the amount of each of the 21 gas components as a percentage.
Gas composition
• Fixed - use the fixed gas composition stored in the meter for all calculations.
• Live GC - use a gas composition collected by the meter from a gas chromatograph
for all calculations. This option is only available with a GC key or is enabled with the
Continuous Flow Analysis key.
• Configure the Gas properties for the gas chromatograph.
• Base temperature.
• Base pressure.
• Specific gravity.
• Specific gravity reference temperature.
• Specific gravity reference pressure.
• Volumetric gross heating value.
• Volumetric gross heating value reference temperature.
• Molar density reference temperature.
• Molar density reference pressure.
• Flow mass density.
(1)
• Flow compressibility.
• Base compressibility.
5.10.3
Configure Continuous Flow Analysis parameters
Configure the Continuous Flow Analysis features of the Daniel Ultrasonic meter. This
Daniel MeterLink
™
Field Setup Wizard page is displayed only if the View Continuous Flow
Analysis setup was selected on the Startup Page and you have a valid Continuous Flow
Analysis key. These features require that the meter baseline be set using the Tools|Set
Baseline Wizard.
(1) If a flow computer or SCADA system is used to write these values to the meter, they do not have to be entered at this time.
