Installing DMP-1
Damping Material
with PI Fixture
1.
Be sure the PI clamping fixture is installed onto the pipe with the transducers as
described in the section
Installing the PI Fixture and Transducers
on page 1-12.
2.
Approximate the axial distance from one transducer face to the other
transducer face, as shown in Figure 1-26 below.
Figure 1-26: Distance Between Transducer Noses
3.
Lay the first strip of damping material flat. Cut a strip to a width equal to the
distance between transducer faces (the distance illustrated in Figure 1-26
above).
4.
Wrap this strip around the pipe in the space between the transducers.
5.
Lay the second strip of damping material flat. Then cut the strip into two pieces,
each 4.5-in. (12 cm) wide.
6.
Wrap each of these strips around the pipe on the outside edge of the clamping
fixture, one upstream and one downstream. The completed installation should
appear similar to Figure 1-27 below.
