Flowmeter, Mech. With One Way Clutch

Weight in water 113 grams (4 ounces) material: celcon rotor, nickel plated brass nose cone, polycarbonbate body, armaloyed stainless steel main rotor and idler gear shaft. Dimensions length 21.3 cm (8 3/8`) diameter: standard rotor 6.98cm (2 3/4`) low velocity 16.5cm (6.5`), depth rating unlimited (free flooding) data display: 6 ten digit counter wheels 000,000 to 999,999 distance determined by difference in begining/ending counts (counter advances through 000,000). 6-digit count 999,999 equals approximately 14.5 nautical miles (standard rotor). Mount: universal bridle allowing single point connecting for towing or two point connection across a net mouth response with the standard rotor-threshold approximately 10cm/sec (1/5 knot). Range 10cm/sec (1/5 knot) to 7.9m/sec approximately (15 knots).
