Principle of Operation

The SR-1101 uses a counting tunnel with metal rings, flush-mounted, on the inner surface. The passage of fish through the counting tunnel causes water conductivity changes. Special logic in the SR-1101 allows it to discriminate between upstream and downstream fish passages. Two six-digit liquid crystal displays (LCD) tally completed fish passages. The displays are easy to read even in direct sunlight.
