8 Mounting the Transducers FLUXUS G60x
UMFLUXUS_G6V4-2EN, 2011-03-29 57
• Depending on the transducer type, another layer of the damping mat is necessary (see
annex B, Technical Data). Repeat the steps for the mounting of the damping mat.
• Mount the transducers onto the damping mat. Select the installation instructions that
correspond to the supplied transducer mounting fixture (see section ...).
• If the measuring point is close to a reflection point (e.g. flange), damping mats must be
installed there, if necessary (see Fig. 8.4). The damping mats are mounted on the
complete circumference of the pipe. Repeat the steps for the installation of the damp-
ing mats.
8.2.2 Mounting of non Self-Adhesive Damping Mats
Observe the operating temperature of the damping mat (see annex B, section Technical
Data).
The non self-adhesive damping mats can be reused. They are not suitable for permanent
use.
A water-based ultrasound gel is used for coupling. The ultrasound gel can dry up and is
then no longer effective.
• Cut the damping mat to size, if necessary (see annex B, section Technical Data).
• Apply a bead of the ultrasound gel on the inner side of the damping mat along the cen-
ter line.
• Spread the ultrasound gel evenly on the surface of the damping mat by means of a
spattle (see Fig. 8.5).
• Position the damping mat on the pipe (see Fig. 8.2).
• Remove air pockets by means of the supplied roller.
