SR-1601 FISH COUNTER

www.smith-root.com

GENERAL DESCRIPTION

The Model SR-1601 Fish Counter features a balanced resis-
tance bridge circuit using the tunnel elements to count fish
in fresh water. Electronic counters simultaneously monitor
up to 16 tubes for downstream fish movements, giving a
“real time” readout for each tube showing count distribution.
The counting heads are interchangeable and are available
with tube diameters ranging from 1/2 to 3 inches. Larger tun-
nels are available on a custom order basis.

PRINCIPLE OF OPERATION

Operation of the SR-1601 Counter is based on the “Balanced
Resistance Bridge Principle” using water in the count head
as two elements of a four element Balanced Bridge. Passage
of a fish through one of the tubes of the count head causes
corresponding changes in that tube’s conductance. These
conductance changes are used by the SR-1601 to sense the
presence of fish in the tubes of the counting head.
