Configure the device identification
Configure the common variables in HART devices used to identify the particular device.
•
Tag - the tag name for the HART device which may be used by host systems to uniquely
identify the meter. The tag may be up to 8 characters in length.
•
Long tag - the specified long tag matches that of the meter. The tag may be 32 bytes in
length.
•
Date - a 3 byte value where the most significant byte is the day of the month (1-31), the
second byte is the month of the year (1-12), and the third byte is the year-1900.
•
Message - a string value that can be no more than 32 characters in length.
•
Descriptor - a string value that can be no more than 16 characters in length.
•
Final assembly number - a numeric value that must be between 0 and 1677215.
•
Polling address - the HART address for the meter. By default the meter is 0 but the address
can range from 0 to 63.
5.8.3
Configure the HART units
Configure the units that values will be read in over the HART interface.
•
Volume units
•
Mass units
•
Energy units
•
Flow rate time units
•
Velocity
•
Pressure
•
Temperature

Configure Meter corrections
Meter profile corrections are used for Daniel 3412 and 3411 Ultrasonic Flow meters only as
shown in
Section 5.9.1
,
Section 5.9.2
and
Section 5.9.3
.
5.9.1
Flow profile correction
Select the profile correction; Fixed, Calculated or Default.
•
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.
5.9.2
Temperature expansion correction
•
Linear expansion coefficient of the meter body material.
•
Linear expansion coefficient reference temperature.
5.9.3
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).
