Award-winning Acoustic Doppler Current Profiler (ADCP) Technology
Introducing the SonTek M9: the ultimate ADCP sensor solution for both discharge data and bathymetric surveys. Combining the durability of the RiverSurveyor-M9 with the adaptability of the HydroSurveyor-M9, this all-in-one ADCP profiler offers unmatched flexibility. Designed to excel in various conditions, from floods to dry spells, it eliminates complicated adjustments with automatic handling. Revolutionizing river and canal measurements, the M9 delivers exceptional performance, including velocity mapping and bathymetric surveys. Pair it with HYPACK Environmental Mapping software for a comprehensive solution in a single system.
- Multiple Acoustic Frequencies (1 MHz, 0.5 MHz, 3 MHz): Balances the highest resolution with the greatest range of depths and flow velocities, making it the ideal ADCP acoustic doppler for varied water conditions.
- Vertical Acoustic Beam, i.e., Echosounder: Superior channel definition for both bathymetric and discharge applications. Extends maximum discharge depth when bottom-tracking is out of range, essential for accurate ADCP current profiling.
- SmartPulseHD®: An intelligent algorithm that evaluates water depth, velocity, and turbulence, then automatically adapts to conditions using pulse-coherent and incoherent techniques. High-definition cell size down to 2 cm, ensuring precision in doppler profiler readings.
- Microprocessor Computed Discharge and Secure Data: Discharge computations using RiverSurveyor Live software are simultaneously done within the M9 and on the host computer. Data integrity is maintained even if communication temporarily drops out.
- Standard 360° Compass and Two-Axis Tilt Sensor: Compensates for vessel motion due to surface conditions, providing velocities in Earth coordinates and magnetic error feedback in real-time and post-processing.
- Ping Rates to 70Hz, Averaged to 1Hz Data Output: High ping rates ensure robust data collection, with ping distribution based on data collection mode – discharge or bathymetry.
- Bottom-Tracking: Acoustically track vessel speed over ground and ship track independent of GNSS/GPS (optional). Also supplies redundant depth measurement, enhancing the reliability of the ADCP profiler.
- Differential GNSS (Optional):* Geo-referenced position from dual-frequency, multi-constellation with SBAS as an alternative to bottom tracking for moving bed or other challenging situations.
- RTK GNSS (Optional):* Ultra-precise geo-referenced position that can be used as an alternative to bottom tracking for moving bed or other challenging conditions. Benchmark tie-in available in HYPACK® software.
- Sound Speed Correction with the CastAway-CTD (Optional): Built-in temperature sensor used for sound speed calculations. Optional use of CastAway-CTD interpolates sound speed in space and time with RiverSurveyor Live and (optional) HYPACK® software.
*GNSS- Global navigation satellite system is a general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis.
