The CSW series are flatbed counters developed for very high capacity counting of fry and smolts.

Registration Units CSW-type consist of a flat and wide counting channel. The fish will be spread out over a flat surface and extra high capacity can be achieved. Used typically for delivery/transport of fish. CSW-series is a compact modular system consisting of 1,2,3 or 4 Registration Units.

They come with special fit racks, and can be used alone or easily be mounted side by side for multiple channels. Unlike the other counter-series, these do not have a pipe installed. The fish will flow freely over the whole scanning area.
