Daniel 3410 Series Ultrasonic Gas Flow Meter Installation Manual Section 4: Configuration
3-9000-759 Rev D June 2014
Field Setup Wizard 75
8. The Meter Corrections page allows you to configure the flow profile, temperature,
pressure and linear expansion corrections, pipe outside diameter The Young’s Modulus
value (ratio of tensile stress to tensile strain) and the Poisson’s ratio value (the absolute
ratio of the pipe material lateral strain over axial strain) for 3412 and 3411 Gas
Ultrasonic Flow meters. Click
Next to continue to the Temperature and Pressure page.
9. Set the temperature and pressure scaling for analog inputs, enter fixed values, and set
alarm limits for both. The alarm limit selections are hold last output value or use fixed
value.
• Live temperature selections include minimum and maximum inputs or fixed
temperature.
• Live pressure selections include minimum and maximum inputs, gage
(atmospheric pressure), absolute, or fixed pressure.

10. Select the settings below to configure a serial port as a Modbus Master to poll a gas
chromatograph.
• 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™ 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: 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. Click Next to
