Appendix B. Using the Clamping Fixtures
102 PanaFlow™ LC User’s Manual
IMPORTANT: Make sure the chains are perpendicular to the clamping fixture and are not twisted. If the chains
are slanted, the slack may cause the fixture to move. Also, the transducer spacing dimension may
change after the transducers are mounted.
Figure 86 below shows a completed even-traverse installation without the transducers. Proceed to the
section on mounting the transducers later in this chapter.

B.1.2 Odd number of-traverse method
Note: The instructions in this section can also be used for a multiple-traverse method. However, you must use
an
ODD number of traverses. The distance the signal travels from one side of the pipe wall to the
opposite side of the pipe wall is considered one traverse. For installations with more than one traverse,
contact BHGE for assistance.
The procedure for mounting the UCF for the odd number of-traverse method requires one long block and two
short blocks. The long block is fastened to the pipe first and then the short block assembly is properly
aligned and fastened 180° around the pipe from the long block.
