| | WATER FLOW METER LABORATORY
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
This Rod is designed to be used with our 2030 series flowmeters. Includes a special tip that mates with the flowmeter which allow the flowmeter to be securely attached to the end of the rod. The flowmeter can be either rigidly attached or allowed to swivel 360 degrees. 3 segments with universal adjustments allow extension from 3 to 9 ft.
