Autonomous data collection for long period of times from Echologger underwater sensors


  • DL3S with echologger sensors
  • DL3S with 3D sonar
  • Echologger DL3S (underwater data logger)
  • DL3S with 2D scanning sonar
  • DL3S with echosounder and scanning sonar
  • DL3S with 3D sonar and GPS

The DL3S underwater data logger stand out in the market as autonomous systems designed for underwater use, offering a range of practical and scientific features. These loggers operate autonomously, collecting real-time data over extended periods from various Echologger underwater sensors, including dual-frequency echosounders, fan beam scanning, and sharp pencil beam 3D sonar.

Echologger's sonar sensors are renowned globally for their role in underwater environmental studies, encompassing applications such as sediment monitoring, wave/tide monitoring, zooplankton studies, and marine structure monitoring. The DL3S serves as a dedicated long-term logging facility for these widely used sensors, ensuring seamless integration with Echologger's popular underwater sensing technologies.

Notably, the DL3S underwater data logger is equipped with embedded sensors, including temperature, pressure, compass, and tilt sensors. This unique feature allows the logger to independently collect valuable information in the water, even without external connections to the specified Echologger sensors mentioned earlier.

In summary, the DS3L and DL3S underwater data loggers offer an autonomous and versatile solution for collecting essential data from Echologger's renowned underwater sensors and embedded environmental sensors. Their capabilities make them indispensable tools for a range of underwater studies and monitoring applications.
