Installing DMP-1 Dampening Material with CFG-V
Series Fixtures
Series Fixtures
1. Be sure the CFG-V clamping fixture is installed on the pipe
with the transducers as described in the section Installing the
V Series Clamping Fixture and Transducers on page 3-8.
With a marker, mark scribe lines on the inside edges of the
brackets onto the pipe. These lines indicate where to apply the
material. (One 9.5-in. roll fits between the brackets.)

2. Remove the fixture and transducers.
3. Use a dry towel or rag and thoroughly dry the pipe.
4. Unroll the DMP-1 material and cut off a length equal to the
circumference. Peel the paper backing off the cut portion.
IMPORTANT: The DMP-1 material will only adhere to the pipe
correctly if the pipe is completely dry. To adhere
properly, the material must also be at a
temperature above 50°F (10°C).

5. Before more atmospheric condensation can occur on the
outside of the pipe, roll the DMP-1 dampening material once
around the pipe, following the scribe marks that represent the
inside edge of the fixture, as shown in Figure 3-23 below.

correctly. Loosely mount the transducers on top of the
dampening material, using the correct spacing.
