10 Basic Measurement
• Cut the damping mat to size, if necessary (see annex A, section Technical Data).
• Apply the a bead of ultrasound gel along the center line onto the inner side of the
damping mat.
• Spread the ultrasound gel evenly on the surface of the damping mat by means of a
spattle (see Fig. 10.6).

• Position the damping mat on the pipe (see Fig. 10.3).
• Remove air pockets by means of the supplied roller.
• Mount the transducers onto the damping mat. Select the installation instruction corre-
sponding to the supplied transducer mounting fixture (see section 10.7).
• If the measuring point is close to a reflection point (e.g. flange), a damping mat has to
be installed there, if necessary (see Fig. 10.5).
• Repeat the steps for the installation of the damping mat.
Note! When measuring in diagonal mode, a damping mat will be fixed addi-
tionally to the opposite side of the pipe (see Fig. 10.4).
Note! Damping mats will be mounted to the complete circumference of the
pipe at the reflection point (see Fig. 10.5).
