Mechanical Flowmeters GO Environmental Ref:Extension Handle 3-8' Venezuela has an immensely richUse 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
