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.
Mounting screws or bolts must not be extruding from the transducer or the plating
immediately around it.
Note
Obstructions on these surfaces will create problems with turbulent flow, and may cause
noise.

Transducer installation using an arctic tank
with acoustic window
Vessels operating in arctic waters need special attention on transducer installation.
Floating blocks of ice may damage even a flush mounted transducer face. For this
situation Kongsberg Maritime offers arctic tanks in different sizes.
Arctic tanks are fitted with special purpose acoustic windows that protect the transducer
face.
The acoustic window is normally manufactured using polycarbonate.
The tank is filled with fluid that consists of 20% propylene glycol and clean water. This
fluid is well suited for this purpose. It contains no gas bubbles and is non-corrosive.
