Programming the 3102 and 3105 using HART
Figure F-2. Two-stage Weir Cross-section
Setting-up procedure for the “Special Plot” option:
1.
Select the displayed (reported) units for the output PV (see
).
2.
Draw the graph of PV versus Liquid Height, and note the maximum points.
3.
Enter the
maximum
liquid height into Profile Height (
4.
Enter the
maximum
volume or flow into PV Scale Factor (
5.
Enter the distance from the transmitter face to the zero point (Y=0) into the
Transmitter Bottom Reference parameter (
).
6.
Use parameters Profile Point 1 (P030) to Profile Point 10 (P039) to enter the percentage
values that relate to the X-axis fixed percentages.
Note
The origin (0,0) is always used as the start point. It is not a parameter.
Note
It is possible that the process value (PV) at the maximum height is less than 100% of the
maximum volume or flow (see
).
