Aga8 Table Generation And Installation Instructions - Siemens SITRANS FUG1010 IP65 NEMA 4X Instruction Manual

Section 4
The table values for temperature must be arranged in ascending order and consist of exactly 10
z
points. The units of entry must be degrees Kelvin.
The table values for Density and Z-factor must be entered for each combination of entered
z
temperature and pressure (100 points for each). The units of entry for density must be Kg/m

AGA8 Table Generation and Installation Instructions

1. Start by first creating the gas composition file within the SonicWare software application.
2. Next customize the output units by selecting PSI absolute and degrees Kelvin.
3. Now determine the application range for pressure and temperature with sufficient margin to insure
that the measured temperature and pressure always falls within the table limits.
4. Compute the temperature increment for 10 points: Tincr = (Tmax – Tmin) / 9, then round off Tincr to
the next higher integer. Now recomputed Tmax = Tmin + 9*Tincr.
5. Repeat Step 4 to compute the pressure increment "Pincr," "Pmin" and "Pmax."
6. From the SonicWare menu select [Perform Range Calculation] and [Varying T & P], then enter the
temperature and pressure range and increments from Steps 4 and 5. Verify that there are exactly
10 "temp. points" and 10 "pres. points" indicated.
7. Select [Density] and [Z-factor] from the output data menu, then click on [Compute].
8. From the SonicWare toolbar select [Table] then [Copy All]. These tables can now be pasted into
EXCEL (see Example #1). Select "General" formatting to remove any commas from the data.
9. The final text file must follow the syntax indicated in the example shown on the next page. To accom-
plish this the data needs to be manipulated within EXCEL and then saved as a comma separated file,
then further modification will be necessary (using a text editor) to obtain the final text file format
shown in Example #2.
NOTE: The data strings must conform to the syntax rules listed below.
10. Save the final AGA8 text file in an appropriate directory on your PC.
11. Now that the file is properly formatted, it can be downloaded to the FUG1010GCN flowmeter using
HyperTerminal or other communication software. With the RS-232 baud rate set to 9600 or lower,
confirm that the meter is properly communicating with the terminal program.
NOTE: If the flowmeter is actively measuring flow the channel must be disabled by either using
the flowmeter keypad or HyperTeminal. In HyperTeminal type: MENU. Select the Chan/
Path menu and then [Channel Enable]. Select the [No] option.
12. Select the desired default channel for download of the AGA8 table. In HyperTerminal type "cv 0" for
Single Channel systems or "cv 2" for Dual Beam systems. Press <ENT>.
13. Select [Send Text File] from the HyperTerminal menu and proceed to transfer the AGA8 compensa-
tion file created in Step 10.
