4 FC1: General Information
4.3.5 FC1: AFB Structure for Special Applications
In a standard AFB composition as described in 4.3.4, the Gas Quality
AFB
is responsible for providing the gas characteristics needed by the
Flow Conversion AFB. The Gas Quality AFB calculates the
compressibility factors according to European standards for natural gases,
e.g. AGA8-92 DC or SGERG-88.
For special applications where industrial gas or gas with a fixed composition
is measured, a
Tabl e Z AFB can be used instead of a Gas Quality
AFB
. The Table Z AFB calculates the compressibility factor Zm at
measurement conditions (p, t) by using a compressibility factor table.
