10 Basic Measurement
• Depending on the transducer type, another layer of the damping mat is necessary (see
annex A, Technical Data). Repeat the steps for the installation of the damping mat.
• 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.

10.6.2 Installation of non Self-Adhesive Damping Mats
Observe the operating temperature of the damping mat (see annex A, section Technical
Data).
The non self-adhesive damping mats can be reused. They are not suitable for permanent
use.
A water based ultrasound gel will be used for coupling. The ultrasound gel can dry and is
then no longer effective.
Note! The damping mat adheres strongly to the pipe. Later alignment is not
possible. The damping mat has to be positioned correctly immediate-
ly.
Note! The damping mat can not be reused after removal.
Note! Damping mats will be mounted to the complete circumference of the
pipe at the reflection point (see Fig. 10.5).
