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
