100 DigitalFlow™ XGS868i Programming Manual
C.5.3 Entering Pipe Parameters
Enter the transducer and pipe parameters via the
Pipe
submenu. While following the programming instructions, refer to
Figure 52 on page 139 of Appendix D, PanaView Menu Maps.
1. From the
Channel PROGRAM
menu, highlight and double-click on the
Pipe Parameters
option in the center pane.
2. The first prompt asks for the Transducer Number.
•
For a standard transducer, double-click on the Standard option in the center pane. Then enter the number
engraved on the transducer head in the right pane, and click
[Next Item].
•
If there is no number engraved on the transducer head, double-click on the Special option, enter an assigned
number (from 91 to 99), and click
[Next Item].
IMPORTANT:
Special transducers, which have no engraved number on the head, are rarely used. Examine the
transducer head carefully for a number.
The menu now varies, depending on your selection in step 2.
•
If you entered the number for a standard transducer, proceed to the Pipe OD prompt in step 4.
•
If you entered the number for a special transducer, proceed to step 3 below.
C.5.3a Special Transducers
3. For special transducers:
Note:
GE Measurement & Control will supply the information required for steps a and b with the transducers.
a. Double-click on the appropriate Frequency (from 25 kHz to 500 kHz).The frequency is required to transmit an
excitation voltage at the transducer’s natural frequency .
b. Enter the Time Delay (Tw) value supplied by GE Measurement & Control and click
[Next Item].
Tw is the time required for the transducer signal to travel through the transducer and its cable. This time delay must be
subtracted from the transit times of the upstream and downstream transducers to ensure an accurate measurement.
