Simrad EK15 Reference Manual page 219

Description
The EK15 is a unique product. One of its many
areas of application is in fish farming. One single
EK15 installation can then be used to monitor the
fish behaviour and food waste in a large number of fish
cages. The transducers are then physically installed
inside the cages with the transducer facing upwards.
The EK15 transducers can also be placed at the seabed in open water - or in a river -
for long-term monitoring of the ecosystem. Due to the fact that several transceivers and
transducers can be connected simultaneously, you can for example establish an acoustic
"fence" to monitor fish passage.
In order to adjust the echogram presentations to this use, the
introduced. Unlike the presentation on a traditional fish finding echo sounder, you can
select Upwards. The presentation is then adjusted for a transducer located at the bottom
of the echogram looking up towards the sea surface.
Parameters
1
Downwards
The echogram presentation on the EK15 is set up as on a traditional fish finding
echo sounder. The sea surface is at the top of the echogram. The transducers are
located close to the surface, and the beams are faced from the top of the presentation
and towards the bottom. Use this presentation when the EK15 transducers are
installed under the hull of a vessel.
2
Upwards
The echogram presentation on the EK15 is turned up-side down. The sea surface is
still at the top of the echogram. However, the transducers are located at the bottom,
and the beams are faced from the bottom of the presentation and upwards towards
the surface. Use this presentation when the EK15 transducers are installed at the
bottom of fish cages or tanks.
