In-Use gas property data
The “In-Use” gas property data is the actual data used by the meter for calculations.
The
GasPropertiesSrcSel data point is used to select the gas property data source as either Fixed
(0) or Live - GC (1). If the data source is Live - GC and the GC-read data is invalid, then the
GasProp-
ertiesSrcSelGCAlarm
data point is used to select the data source as either Last good value (0) or
Fixed value (1). When Last good value is selected, the “In-Use” gas property data is not updated
with the invalid GC-read gas property data. When Fixed value is used, the “In-Use” gas property
data is updated with the fixed gas property data.
The meter maps the appropriate input gas property data points (fixed or GC-reported as
discussed above) to the corresponding “In-Use” data points (the
HeatingValueInUse data point
and the gas composition data points listed in the Ta bl e 5 -1 0 below).
The fixed gas component data points map directly to the corresponding “In-Use” gas
component data points. The GC-reported gas component data points map directly to the
corresponding “In-Use” gas component data points except for the
C6PlusGC and NeoPentaneGC
components. The
C6PlusGC quantity is divided among the NHexaneInUse, NHeptaneInUse, and
