Flow Tank

This is a 42 ft long x 10.5 ft wide x 4 ft deep (12.8 m x 3.2 m x 1.2 m) oval fiberglass tank with a center divider and end-mounted electric motors that provide a controlled flow system for a variety of studies. This unique tank has computer-controlled variable speed motors, which allow for a variety of functions, including simulating fluctuating currents due to tidal cycles. For sample and device testing, the tank has two flow channels that are 5 ft (1.5 m) wide, 4 ft (1.2 m) deep, and ~30 ft (9.1 m) long. The flow tank is connected to a continuous unfiltered-seawater input, which allows researchers to study antifouling coatings on everything from small coupons up through scaled devices under a range of velocities and orientations relative to current. The tank also has mounting racks so that several hundred coupons can simultaneously be exposed under identical conditions. Finally, it has water monitoring systems that track temperature, salinity, velocity, toxicity, pH and more.
