6.2 Creating an AGA-8 Table
An AGA8 compensation table can be created in the FS200 Utility. When uploaded to the
FS230 Gas Flowmeter, table data will facilitate standard volume correction based upon
measured temperature and pressure over the complete range of your application.
Note that this table is most accurate for fixed gas compositions. If gas properties vary
considerably, compressibility compensation factors will change resulting in a decrease of
meter accuracy.
Table data can be sent to the FS230 gas flowmeter by selecting the [Send Table] button. If
the flowmeter is not a gas meter the [Send Table] button will be grayed out.
To Create an AGA8 Table
1. Using the same data you entered in the AGA8 screen earlier (see example in Figure 6-
2), check the [Create AGA8 Table] box at the top right corner of the screen. This action
will remove the Enthalpy data but keep your gas composition entries intact.
2. Enter your application’s Minimum / Maximum and Base pressure and the Minimum /
Maximum / Base temperature in the appropriate fields
3. Click the [Calculate] button to generate the AGA8 table as illustrated in Figure 6-3 below
4. Since the FS230 gas meter operates from a default AGA8 gas table you must first erase
the default table before uploading your custom table. Therefore, to upload the table to
the meter, first click the [Erase Flash] button then click the [Send Table] button
