River Discharge Measurement SystemRiver Discharge Measurement System
Hoboken, NJJune 2012
•New Doppler engine
•New transducer configurations
•New multiple frequency configurations
•New automated cell-size switching and signal processing (SmartPusleHD)
•New housings and power-communications modules
•New PC and mobile software
•New high-resolution GPS options
•New floating platform
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.

S5/M9 Measurement DistributionS5/M9 Measurement Distribution
The S5/M9 pings up to about 80 Hz.The S5/M9 pings up to about 80 Hz.
Pings are distributed between Bottom-tracking (BT), Water Profiling Pings are distributed between Bottom-tracking (BT), Water Profiling (WP), Vertical-Beam (VB) to optimize measurements.(WP), Vertical-Beam (VB) to optimize measurements.
Typically BT pings at 5 Hz.Typically BT pings at 5 Hz.
WP pings depend on frequency and depth.WP pings depend on frequency and depth.
