2.5 TRANSDUCER MOUNTING INSPECTION AND COUPLANT
APPLICATION
2.5.1 Transducer Mounting Inspection
It is very important to use menu operations for TRANSDUCER MOUNTING
INSPECTION and Estimation, Refer to
5.16, Use menu windows for Transducer Mounting
Inspection.
2.5.2 Couplant Application
A, It is also very important for couplant application.
When mounting the transducers, apply just enough pressure so that the couplant fills the
gap between the pipe and transducer. Commonly, the Dow 732 for permanent and Dow 111
for temporary installations, but Dow 111 has a better coupling effect. If Dow 732 was used,
ensure that no relative movement between the transducer and the pipe takes place during
the setting time and do not apply instrument power for at least 24 hours, Dow 111 also be
used for permanent installations(avoid rain or water etc.), setting time is not necessary. We
recommend using Dow 111 for permanent installing, and then use Dow732 around the
transducer in order to fix the transducer, waterproof cloth is recommended if the
Transducers are installed outdoor. Dow 112 for high temperature application.
B, Transducers for High Temperature
Mounting of high temperature transducers is similar to TF1100 standard transducers; High
temperature installations require acoustic couplant Dow Corning 112 that is rated not to
flow at the temperature that will be present on the pipe surface.
