General Ocean Mechanical Flowmeter.

Can also be used with a plankton net in determining water volume Use in rivers, estuaries, canals, sewer outfalls, pipes, and harbor entrances to determine velocity and distance information or use with plankton nets to determine water volume associated with each tow. Both models incorporate precision molded rotors coupled directly to six digit counters which record each rotor revolution. Supplied with a standard calibration curve (number of counts/unit time vs. velocity) sealed inside transparent body. A single pin and lanyard system located ahead of the lateral center of mass allows the flowmeter to maintain correct dynamic alignment with the fluid flow in which it is immersed.

Materials
Celcon rotor, nickel-plated brass nose piece, poly-carbonate body, stainless steel main rotor and idler gear shafts, Delrin idler gears, and Delrin and nylon digit wheels.  

Dimensions
Overall length is 8-3/8" with a 1-9/16" dia. body.

Depth Rating
Unlimited (free flooding).

Data Readout
Six 10-digit counter wheels read 000,000 to 999,999; 10 counts per rotor revolution, non-resetting; read by noting difference in start and end readings (counter advances through 000,000).

Six-digit full scale count:
999,999 counts equal approximately 14-1/2 nautical miles (1,852 meters/nautical mile).

Mounting
Universal bridle allows single point connection for towing or two point connection within net mouth.  

Response with standard 3" dia. rotor
Threshold approx. 10 cm/sec. (1/5 knot).
