For example, if the C
6
PlusGC mole percentage is 1% and its component ID is 110, then 60%
of the C6+ 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 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.
