The rated operating conditions applying to the various conversion methods are described
in Chapter 4.1.

Conversion factor

The conversion factor is calculated according to the following formula:

(

3.4,

3.5,

: see below)

Compressibility factor ratio (K-value)

The K-value is used for computing the conversion factor (see above). It is calcu-
lated according to the following formula:

where z = compressibility factor and z

= compressibility factor at base conditions.

The computation of z and zb takes place according to S-Gerg-88 or AGA-NX19,
depending on the setting of

Md.K

. The gas analysis values

Ho.b

CO2

and

Rhob

(

Md.

K = 1), resp.

and

(

Md.K

= 2, 3 and 4) need to be included in the

entries for this (

3.6).

If the K-value mode

Md.K

(see below) is set to "fixed value" (= "0"),

is not com-

puted, but the substitute value

K.F

(see below) is used instead.

pbX

Pressure at base conditions for gas analysis input

TbX

Temperature at base conditions for gas analysis input

The base condition described by pbX and TbX is valid for the gas analysis input
(Ho.b, CO2, … dr, see below) only. By contrast, the conversion factor C (

3.6)

and the volume at base conditions Vb (

3.2) will be computed using the base

condition described by pb and Tb (

3.4 resp. 3.5).

Any change of pb or Tb will change pbX resp. TbX to the same value. To get di f-
ferent values, change pbX or TbX after pb or Tb.
