Live (GC) gas property data
The purpose of this section is to give a brief overview of the gas property data read from a GC.
Refer to Section 2.1 for information on configuring the Daniel 3410 Series Gas Ultrasonic Flow
Meter (using the Daniel MeterLink program) for communicating with a Daniel GC.
If the gas components are read from the GC, then the GC-reported heating value is readable via
the
HeatingValueGC data point. Note that type of heating value to be read from the GC must be
specified via the
GCHeatingValueType data point as either Btu-Dry, Btu-Saturated, or
Btu-Actual.so that the correct GC register is read. Also, the heating value unit must be specified
via the
GCHeatingValueUnit data point as either Btu/ft

. The GC-reported gas composition is readable via the data points listed in Ta bl e 5 -9 below:
The validity of the GC-read gas property data is readable via the
AreGasPropertiesInvalidGC data
point where TRUE(1) indicates invalid data and FALSE(0) indicates valid data. Refer to GC data
validity for further information on how the data validity is determined.
