Fill with suitable filling
compound (putty) to
reduce flow noise
Procedure
1
Lift the transducer up into
is location, and align the
holes on the transducer
with the threaded rods welded to the fairing.
Observe the direction of the transducer. The "forward" marking must point towards
the bow of the vessel!
2
Push the transducer in place.
3
Fasten the two nuts on the end of each threaded rod.
Use Loctite 290 to secure the bolts.
4
Fill the two bolt holes in the transducer with a suitable filling compound (putty),
and smooth out the surface of the transducer face.
Any obstructions, cracks, dents or unevenness on the transducer face may cause
flow noise.
5
When the transducer has been fastened, inspect the plating around the transducer
face.
Important
Make sure that the surface of the transducer face, as well as the plating and putty
around the transducer is as even and smooth as possible. Obstructions on these
surfaces will create problems with turbulent flow, and may cause noise.
6
If required, allow the relevant maritime authority and/or classification society to
inspect and approve the transducer installation.
