Advancements:

S5 & M9 Acoustic Doppler ProfilersS5 & M9 Acoustic Doppler Profilers

• Significantly faster ping rates (20-60 Hz) - robust and accurate measurements.

• Integrated multiple acoustic frequencies.

• Integrated acoustic vertical beam transducers – for depth.

• SmartPulseHD – transitions water-profiling automatically.

• Large internal recorder (8 Gb) - Discharge processing and data storage is done inside the ADP and in software.

• Increased Processing Power for discharge calculations, real-time data quality checking, on-line summary tables, etc…

• Dramatically improved bottom tracking resolution and precision.

RiverSurveyor S5 & M9 RiverSurveyor S5 & M9 Enhancements for the user Enhancements for the user

• SmartPage Setup – Guided setup and configuration.

• SmartPulseHD – automatically adjusts water velocity measurement technique to adapt to changing river conditions. Requires “NO” user-based setup or configuration.

• Moving-bed tests – USGS “Loop-method” and USGS “SMBA-method” included in software.

• Redundant depth measurements with low-frequency vertical beam.

• High-resolution GPS system integration – ease of use and setup.
