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 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
