This facility is primarily used for the calibration of mechanical current meters and large acoustic meters. Examples of meters calibrated in the towing tank are: mechanical rotating cup meters, both vertical and horizontal axis type meters; electromagnetic meters, one- and two-dimensional; acoustic time of travel meters; three-dimensional acoustic Doppler meters; and three-dimensional acoustic Doppler current profiling meters.
The towing tank has a 12 x 12 ft cross section and is 450 ft long. The tow vehicle is capable of speeds from 0 to 15 ft/s (feet per second), and has a platform size of 12 x 14 ft. The carriage is equipped with a data acquisition system designed to accept distance traveled, elapsed time, and meter pulse count information.
