3.3.5 SONIC COUPLING COMPOUND RECOMMENDATIONS
Clamp-on transducers must be in close contact with a smooth surface free of paint, etc. You
must use a sonic couplant to properly couple the transducer to the pipe. The sonic couplant
material fills voids between the transducer and pipe and allows a uniform transfer of sonic
energy into the pipe wall. The following table lists the sonic couplants recommended by
Controlotron.
Notice: Controlotron holds US Patent Number 4,929,368 on the CC#122 Coupling Compound
and all compounds of this type. Its use is restricted to Controlotron products only, un-
less a special license has been obtained. Licenses for use with other products are avail-
able through the Controlotron Sales Department.
