What is an adv file and how do I open an adv file?

The ADV file extension is a data format associated to Nortek Acoustic Doppler Velocimeter, a high resolution three- dimensional instrument used in the laboratory or ocean. ADV files and Nortek Acoustic Doppler Velocimeter were developed by Nortek. These files contain data measurements of water, particles, and other matter found in the laboratory. Nortek’s three dimensional instruments include Vector, Vectrino and Vectrino II. Vector measures 3D velocity, used for turbulence, boundary layer measurements, and surf zone measurements in very low flow areas. Vectrino measures turbulence and 3D velocities in hydraulic laboratories.  Vectrino II measures turbulence and 3D velocities with a 3 cm profiling zone. Files in ADV format can be opened with Nortek WinADV in Microsoft Windows-based systems. Data gathering can be done via online systems such as Cabled, Acoustic modem, Seastate and Autonomous Online System. Cabled system means using cables and connectors to the instrument. Acoustic modem means using a modem without cables to send data.
