SCT counting tunnels can be used by both the SR-1101 and the SR-1601
fish counters. The SR-1101 counts with only one tunnel but is able to
discriminate between upstream and downstream fish movements. Conversely,
the SR-1601 counts up to sixteen tunnels but does not discriminate
between upstream and downstream fish movements.
The standard SCT-1, 2, & 3 counting tunnels are 1", 2", and 3"
diameter respectively. They all have a tapered entrance to prevent
abrasive damage to fish. Counting tunnels are fabricated from PVC with
stainless steel electrodes.
