Installing DMP-1 Dampening Material with CFG-V

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.

6. Reinstall the fixture, and make sure the spacing is set

correctly. Loosely mount the transducers on top of the

dampening material, using the correct spacing.
