AquaScan fish counters are based on a patended measuring principle which delivers both high capacity and accuracy. The fish flows through a pipe and passes an advanced sensor that registers its size and speed.

1. Accurate. Reliable. Efficient.
AquaScan manufacture and sell electronic measuring equipment used for counting
fish being transported in pipes.
We have a wide range of counters ready to meet the demands from the smallest fish
farms to the largest well-boats and processing plants.
Our fish counters utilize state of the art imaging technology, electronics and software
to ensure that the operators are always provided with precise information.
In addition to the impressive accuracy of our counters, it is also important for us to
deliver durable units able to work flawlessly in the harsh marine environment for
years.
Our counting systems are easy to use, easy to move and get the job done quickly
and accurately with a minimum of manpower.
It doesn´t have to be complicated to be high tech. It´s simple really:
Accurate.Reliable.Efficient.

2. Unique Technology
AquaScan fish counters are based on a
patended measuring principle which delivers
both high capacity and accuracy. The fish
flows through a pipe and passes an
advanced sensor that registers its size and
speed.
The large amount of registered data is
continuously transferred to a Control Unit,
which will process data from up to 4 counters
at the same time.
The system is not dependent on the fish
passing one by one. When several fish
pass the sensor at the same time, the
Control Unit will use a continuously
updated average weight as a base for
calculating the correct number and size of
the fish.
Advanced electronics and software
ensures that the number and size of the
fish are always reliable.

3. COMPANY HISTORY
Our patented measuring principle was developed by company founder and general manager
Torbjørn Kvassheim.
It started with his thesis work at the regional university in
Stavanger, Norway in 1989. The measuring principle
represented a new method of counting where the distance
between the objects passing the sensor was no longer
relevant. This made it possible to start producing fish
counters of high capacity and accuracy, and the company
was founded in 1990.
After the original AquaScan C-series smolt counter had
become a hit in the early 1990´s, the international market
was now demanding a way of fast and accurate counting for
fish of different sizes and species. This resulted in the
development of the CS-series, specifically designed for
counting fish being transported in pipes.
The CS-series became a great success, and in 2000 the CSE-
series saw the light of day. Directly based on its predecessor, the
CSE-series had a much tougher and service friendlymodule-
based construction. The CSE-series are still our best sellers, and
they have been upgraded several times since the first units.
The CSF-series was also developed in the early 2000´s.
They were made for a heavier market, where the need for
moving and counting enormous amounts of fish very fast
was a key factor. These counters are used in pipe
systems where the pipes are completely filled with water.
They have two sensor modules, which allow them to see
the fish from two different angles.
In the late 2000´s, the CSW-series made its way to the
customers. These smolt-counters are somewhat different from
the others, as they have no need for a pipe inside. The fish will
flow through freely using the full width of the sensor area. This,
and state of the art high resolution cameras, makes them very
efficient for counting large amounts of smaller fish.
