2.6.1 Even number of Traverse method
Note: The instructions in this section can also be used for a
multiple-traverse method. However, you must use an EVEN
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
two traverses, contact Panametrics for assistance.
The installation procedure for transducers using the even
number of-traverse method is as follows:
1. Ensure the location of your clamping fixture has been
properly scoped out following the criteria in Section 2.6:
Precautions.
2. Prepare the pipe where you intend to place the
clamping fixture by making sure it is clean and free of
loose material. Sanding, though usually not required,
may be necessary to remove any high spots. However,
be careful to preserve the original curvature of the pipe.
3. Secure one of the blocks to the alignment bar by
tightening one of the nuts on the block so the block will
not be able to slide along the alignment bar’s slot.
4. Obtain the transducer spacing dimension (S) after
programming the XMT1000 transmitter. Using the
alignment bar as a guide, move the second block so
that the distance between the blocks equals the S
dimension. Use the pressure bolts or the edges of the
blocks as reference points, as shown below.

5. Position the clamping fixture on top of the pipe and
wrap the clamping fixture blocks with the hose clamps.
Tighten the clamps until the blocks are snug but ensure
that they can still be rotated around the pipe.
6. Rotate the blocks so that they are away from the vertical
plane and in an orientation that satisfies the criteria
listed in Section 2.6: Precautions.
7. Fully tighten the hose clamps so no movement on the
fixture will occur.
Figure 9 below shows a completed even-traverse
installation without the transducers. Proceed to the section
on mounting the transducers later in this chapter.

2.6.2 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 Panametrics for assistance.
The procedure for mounting the SCF for the odd number of-
traverse method includes marking the pipe for the required
transducer spacing, fastening the fixture to the pipe, and
then mounting the transducers into the fixture.
To install the SCF odd traverse, complete the following steps:
1. Ensure the location of your clamping fixture has been
properly scoped out following the criteria in Section 2.6:
Precautions.
Note: For simplicity, all figures will show the clamping fixture
oriented on the horizontal plane (3 o’clock and 9 o’clock
positions). Exact orientation will depend on the piping
upstream and downstream of the fixture determined in
Section 2.6: Precautions.
2. Prepare the pipe where you intend to place the SCF
by making sure it is clean and free of loose material.
Sanding, though usually not required, may be necessary
to remove any high spots. However, be careful to
preserve the original curvature of the pipe.
