General Oceanics Mechanical Flowmeter Model 2030R6 w/6-3/4” Dia. Rotor

Model 2030R6 – Flowmeter with gray PVC slow speed, low velocity (6 to 100 cm/sec) 6-3/4” dia. rotor 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.
