AML-3 Sound Velocity Profiler

AML-3 Sound Velocity Profiler

Model:AML-3

The AML-3 Sound Speed Profiler uses Time-of-Flight technology to measure sound speed, while pressure is measured via a semiconductor strain gauge transducer. The AML-3 Sound Speed Profiler connects directly to a computer for immediate data export. Each sensor includes internal calibration coefficients and real-time data output, ensuring true plug-and-play operation. Sound speed profiles in water are critical physical parameters for sonar systems. These profilers are widely used in civil applications such as oceanographic surveys, underwater mapping, and underwater navigation and positioning.
