Gas properties

NOctaneInUse
data points according to the component ID (
C
6
PlusGCComponentID
) as listed in
Table 5-11
below:
For example, if the
C
6
PlusGC
mole percentage is 1% and its component ID is 110, then 60% of the
C
6
+ mole percentage (0.60x1%=0.60%) is added to
NHexaneInUse
, 30% (0.30x1%=0.30%) is
added to
NHeptaneInUse
, and 10% (0.10x1%=0.10%) is added to
NOctaneInUse
.
The GC-reported NeoPentane component (
NeoPentaneGC
) quantity is added to the IsoPentane
component (
IsoPentaneInUse
).
The validity of the “In-Use” gas property data is readable via the
AreGasPropertiesInvalidInUse
data point where TRUE(1) indicates invalid data and FALSE(0) indicates valid data. The validity of
the “In-Use” gas property data is a function of the validity of the selected source data. If the
source data is selected as
Fixed
, then the “In-Use” gas property data is valid (since the fixed data
is assumed to be valid). If the source data is selected as
Live - GC
, then the “In-Use” gas property
data is valid only if the GC-read gas property data is valid.
Optional gas chromatograph interface
The Daniel 3410 Series Gas Ultrasonic Flow Meter can optionally interface with any Daniel gas
chromatograph (GC) that supports the SIM 2251 mode to read gas property data (such as for
AGA8, AGA10, energy rate, mass rate, and/or 3412 or 3411 profile correction calculations).
The following table lists the Gas Chromatograph SIM registers polled by the meter. Also refer to
Daniel Engineering Specification Part Number ES-17128-005 Rev. B.

The gas chromatograph interface is an optional feature that requires a valid GC feature key (
see
Section 3.1.2
).
