• If Live or Fixed is selected on the Daniel MeterLink Startup page, for both
temperature and pressure enter a value from 0.9 to 1.0 for Fixed correction factor.
• If Not used was selected for either temperature or pressure on the Startup Page,
then choose from Fixed or Default for a correction factor. Calculated will be
disabled. Enter a value from 0.9 to 1.0 for Fixed correction factor.
• Default - The default value is 0.95.
5.8.2 Temperature expansion correction
• Linear expansion coefficient of the meter body material.
• Linear expansion coefficient reference temperature.
5.8.3 Pressure expansion correction
• Pipe outside diameter: enter the outside diameter of the meter body.
• Young's modulus: enter the Young's Modulus value (ratio of tensile stress to tensile
strain).
• Poisson's ratio: enter the Poisson's Ratio value (the absolute ratio of the pipe
material lateral strain over axial strain).
5.9 Configure Temperature and Pressure
5.9.1 Flow-condition pressure and temperature
The flow-condition pressure and temperature are used by the Daniel 3410 Series Gas
Ultrasonic Flow Meter for various calculations such as:
• Expansion correction
• Flow profile correction (JuniorSonic
™
meters only)
• Calculation of base (standard) condition volumetric flow rate and volumes
• optional AGA10 sound velocity calculation
Configuration
The flow-condition pressure and temperature are individually configurable (via the
EnablePressureInput and EnableTemperatureInput data points) to be:
• Disabled (0),
• Live (1) (4-20 mA input signal)
• Fixed (2).
If an input is live, then the values corresponding to the minimum and maximum input (4
and 20 mA, respectively) are specified via data points (MinInputPressure,
MaxInputPressure, MinInputTemperature, MaxInputTemperature).
