chromatograph. See Serial Connections
• Serial Port: select which serial port will be connected to the GC. While the port is
configured for communications to a GC, it will not act as a Modbus slave device
for communications from Daniel MeterLink
GC protocol: select the protocol for which the GC is configured. The Daniel Gas
•
Ultrasonic meter uses 7 data bits, Even parity, and 1 stop bit for ASCII Modbus
and 8 data bits, No parity, and 1 stop bit for RTU Modbus.
• GC baud rate: select the baud rate for which the GC is configured.
GC comms address: enter the Modbus ID of the GC.
•
• GC stream number: enter the stream number for the gas composition the Daniel
Gas Ultrasonic meter will read.
GC heating value units: elect the units for which the heating value is configured
•
in the GC.
• Use which gas composition on GC alarm: select which gas composition the
Daniel Gas Ultrasonic meter will use if the GC goes into alarm. If Fixed value is
selected, the meter will start using the fixed gas composition stored in the
meter. If Last good value is selected, the meter will use the last gas composition
collected from the GC before the GC started to report alarms.

This page is only displayed for Daniel Gas Ultrasonic meters if both temperature and
pressure are set to Live Analog, Fixed and Base condition correction is selected on
the Startup Page. Configuration parameters include:
• Calculations performed internally (by the meter) or Externally
• AGA8 method - Gross Method 1, Gross method 2, Detail or GERG-2008
• GC composition source - Fixed, Live GC
• Base temperature and pressure
• Specific gravity - reference temperature and pressure
• Volumetric gross heating value and reference temperature
• Molar density reference temperature and pressure
• Flow Mass density, flow compressibility and Base compressibility
• Gas composition inputs - components and mole percent
to configure port as Read-only.
