Before you begin the installation, make sure you note the
application information in Table 2 below for your clamping
fixture. The UCF is available in 12” (300 mm) and 24” (600
mm) lengths. Both lengths can be used for either odd
traverse or even-traverse installations, but you must
observe the pipe size ranges shown.

The transducer installation consists of mounting the UCF to
the pipe and then mounting the transducers into the fixture.
Refer to the appropriate section for instructions on either the
even-traverse or odd number of-traverse methods.
B.1.1 Even 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.
There are two advantages to using the even number of-
traverse method:
• Measurement accuracy is improved because the
ultrasonic signal is in the fluid longer than with an odd
number of-traverse method.
• If there is enough pipe length available, the even-
traverse fixture is easier to install.
The procedure for mounting the UCF involves setting the
transducer spacing and fastening the fixture on the pipe.
Note: For a even-traverse installation, you will only need the
short block assembly - the long block is not used.
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. Obtain the transducer spacing dimension (S) after
programming the XMT1000 transmitter. Using the
attached ruler on the slide bar as a guide, move the
adjustable 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.

4. Position the clamping fixture along the horizontal plane
of the pipe. It must not be on the top or bottom of the
pipe. Make sure the chains on both blocks are on the
side of the fixture opposite from the slide bar with the
ruler.

5. Wrap one of the chains around the pipe and fasten it
on the J screw hook on the opposite side of the block.
Repeat this for the other chain.

6. Using the screw hook on the blocks, tighten both chains
until the fixture is secured snugly to the side of the pipe.
