The Simrad EK15 is designed for
a variety of applications, and for both mobile surveys and fixed locations.
You can put it to use in a wide variety of environments: lakes,
fjords, harbours, shallow marine, rivers, and even in aquaculture
fish cages. The unique functionality offered using numerous transceivers,
raw data logging and interfaces to secondary systems allow you to
use the EK15 for fish stock assessment, studies of fish behavior and
fish-plankton interactions, habitat mapping and ecosystem monitoring.
The Simrad EK15 is based on a small and ruggedized single beam Transceiver
Unit and a dedicated transducer. The operational frequency is 200
kHz, which offers a very high resolution and high accuracy. You can
use the Simrad EK15 with up to 15 Transceiver Units. These will operate
in parallel with either simultaneous or sequential pinging. Using
multiple transceivers you can monitor large areas with only a single
echo sounder system.
Due to the fact that the echogram presentation
on the Simrad EK15 can be turned “upside down”, the sounder
is the ideal solution if you need to monitor a large number of fish
cages. One transducer can then be placed at the bottom of each fish
cage looking up. You can also set up a custom EK15 system to create
an “acoustic fence”. Such “fences” are in
frequent use to monitor the water inlets in a hydropower dam. A similar
system can be used across a river or a fjord if you research fish
migration, or simply needs to check the habitat and the occurrence
of marine life.
You can also set up the Simrad EK15 for wireless
communication between the computer and the Transceiver Units. This
is a good solution for both portable and fixed installation systems
as the amount of cabling is greatly reduced.
