Pressure reading - Select either Gage or Absolute for the type of pressure reading
desired. If a live pressure transmitter is connected, select the type of reading the
transmitter outputs. If Absolute is selected, you must also enter the Atmospheric
pressure.
Live pressure - Enter in the scaling for the transmitter connected to the analog input.
Min. input is the zero scale pressure of the transmitter (i.e. 1 Volt or 4mA). Max.
input is the full scale pressure of the transmitter (i.e. 5 Volts or 20 mA).
Fixed pressure - Enabled if Fixed was selected for Temperature for meter corrections
on the Startup Page. It will also be enabled if a live temperature input was selected
to allow you to enter a fixed value to use for calculations if the live input goes into
alarm. Enter an average pressure of the process fluid.
Pressure alarm - Enter the low and high alarm limits. A pressure reading outside of
these limits causes a Pressure Validity alarm. The Alarm selection determines what
value to use while a live input is in alarm. This value is common with the temperature
Alarm selection so when one is changed, the other will change to match.
Port - Select which port will be connected to the GC. While a serial port is configured
for communications to a GC, it will not act as a Modbus slave device for
communications from Daniel MeterLink or a SCADA system
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/unit identifier - Enter the Modbus ID of the GC.
GC IP address - This option will be enabled only when the Ethernet is selected.
GC TCP/IP port number - This option will be enabled only when the Ethernet is
selected.
GC stream number - Enter the stream number for the gas composition the Daniel
Gas Ultrasonic meter will read.
GC heating value units - Select the units for which the heating value is configured in
the GC.
