ADVANCED FEATURES
The SR-1601 employs numerous advanced features provid-
ing such functions as to simultaneously monitor 16 different
tunnels giving real time distribution of counts. The counts
are displayed on liquid crystal displays (LCDs) which provide
easy readability even in direct sunlight. The count is retained
by internal display batteries if power to the fish counter is
lost. Also included is a wide-range sensitivity control which
provides the ability to set the size of the smallest fish that
will be counted.
WATER CONDITIONS
The counter is designed to work in fresh water with a con-
ductivity of 10 to 500 microsiemen. The 16 tube counting
head must be completely submerged in fresh water and an
appropriate water head developed to overcome the swim-
ming ability of the fish to be counted. The fish are then
crowded into the vicinity of the tube entrances where they
are pulled through and counted. With proper tube size and
water flow, count accuracy is better than 98%.
