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 5.2 for information on configuring the Daniel Mark III Ultrasonic Gas Flow Meter (using the Daniel MeterLink program) for communicating with a Daniel GC. Refer to Section 6.5 for detailed information on interfacing the Daniel Mark III Ultrasonic Gas Flow Meter meter 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/ft3, kJ/m3, kJ/dm3, MJ/m3, kCal/m3, or

kWh/m3. The GC-reported gas composition is readable via the data points listed in Table 6-8below:
