Mechanical Flowmeters GO Environmental

$ 587.50 USD

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. The ref. 2030R6 with a rotor of 7 in, is ideal for slow water (6 to 100 cm/sec) and ref. 2030R with a rotor of 3 in, is ideal for faster water (10 to 790 cm/sec).

Available extension handle for use of mechanical flowmeters in streams and moving water. 8 feet extends up to measure the flow of current hard to reach. Sold separately.

• • Data readout: Six 10-digit counter wheel reading 000000 to 999999. Ten counts per rotor revolution, non-resetting. Read by noting difference in beginning and end readings. Counter advances through 000000. 999999 counts equals approximately 14.5 nautical miles.
  • Speed Range: With standard rotor, approx. 10cm/sec (1/5 knot) to 7.9 meters/sec (15 knots).
  With low-speed rotor, approx. 6cm/sec (3/25 knot) to 100cm/sec (2 knots).
  • Mounting: Universal bridle allowing single-point connection for towing or two-point connection within net mouth. 3-point connection ring is also available as an option. High-speed impeller rotates clockwise, low-speed impeller rotates counterclockwise.
  • Weight in Air:  225 grams (8 ounces).
  • Weight in Water: 113 grams (4 ounces).
  • Materials: Polycarbonate body, Celcon impeller, nickel-plated brass nose cone, Armalloyed stainless steel rotor and idler gear shafts. PVC low-speed impeller available as an option.
  • Dimensions: 21.3cm (8 3/8”) overall length. Standard rotor diameter is 6.98cm (2 3/4”). Low-speed rotor diameter is 16.5cm (6 1/2”).
  • Depth Rating: Unlimited (free flooding). Standard order of a 2030 series flowmeter includes universal bridle, standard or low-speed rotor. Standard order of a 2031 series flowmeter includes universal bridle, standard or low-speed rotor and pigtail (short length of cable and underwater connector for connection to readout cable. Readouts and other options to be ordered separately.

Advanced Stream and Flow Monitoring with the General Oceanics Mechanical Flowmeter

The ultimate tool for measuring water velocity and volume in aquatic ecosystems, designed to deliver rigorous data in rivers, estuaries, and plankton studies at any depth.

The 2030 series mechanical flowmeter is an indispensable precision instrument for researchers and professionals dedicated to studying water dynamics in nature. Its hydrodynamic design, equipped with a pin and lanyard system, ensures perfect alignment with the current, eliminating errors caused by turbulence. Whether determining the volume of water filtered in plankton nets or mapping velocity in canals and harbor entrances, this device provides a reliable direct reading through its six-digit counter, operating optimally even under full immersion and continuous flow conditions.

Key Features

• High-Precision Rotors: Available in versions for slow and fast waters, adapting to various natural environments.
• Continuous Data Logging: Six-digit counter records every rotor revolution for an exact distance calculation.
• Dynamic Alignment: Balanced suspension system that keeps the instrument correctly oriented toward the fluid flow.
• Scientific Grade Construction: Polycarbonate body and Armalloyed stainless steel shafts resistant to corrosion in fresh or salt water.
• Depth Versatility: Free-flooding design that allows operation without pressure limits in deep water columns.
