Transducer installation in keel box
Vessels with a keel box may use this for transducer installation. The keel is already the
deepest part of the vessel. If the keel is too narrow to accommodate the transducer, it
can be widened, either symmetrically or to one side only. If the keel width is increased
to one side only, the installation principle could also be regarded as a blister merged
into the keel.

Using the mounting ring
This large circular is
transducer is designed
to be mounted using
the integrated flange
and a mounting ring.The
mounting ring is welded to the hole prepared for the transducer. Bolts through the
transducer flange into the mounting ring will secure the transducer in place.
Note
Make sure that the "Forward" direction on transducer points in the forward direction
of the vessel.
A suitable mounting ring can be provided by Kongsberg Maritime. A drawing is
available for local manufacturing. End user manuals and source drawings (normally in
AutoCad format) can be downloaded from our website.

Smooth surface is 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.
