River-ADCP-M9

9-Beam Riverine ADCP, Engineered for Shallow Water Flow Measurement

Lightweight & Portable, Perfect for Shallow Water, Multi-scenario Flow Measurement

Key Features: Dual Frequency 9-Beam River ADCP

Multi-Beam, Dual-Frequency River Profiling
Designed for complex river environments, with a 9-beam configuration combining dual-frequency Janus arrays and a dedicated vertical depth-measuring beam. Delivers full-section velocity and bathymetry data in a single pass.
Ultra-High Precision Flow & Discharge Measurement
Provides industry-leading velocity accuracy (±0.25% ±2 mm/s) and 1 mm/s resolution, supporting ±20.0 m/s maximum flow speeds and 0–360° directional sensing, ideal for accurate river discharge calculations.
Wide Profiling & Depth Coverage
Offers flexible profiling ranges from 0.06–40 m and bathymetric coverage up to 80 m, suitable for shallow to medium-depth rivers, braided channels, and variable-bed conditions.
Integrated Bathymetry & Topographic Mapping
Combines velocity profiling with depth and bathymetric measurement, enabling simultaneous flow and riverbed topography surveys to support hydrological modeling and river engineering projects.
GNSS-Enabled Positioning for Mobile Surveys
Integrated GNSS/GPS compatibility supports georeferenced discharge measurements from moving vessels, enabling efficient cross-section surveys and long-reach river monitoring.
High-Resolution & Customizable Profiling
Adjustable cell layer thickness (0.02–4 m) and up to 255 measurement layers, paired with a 2 Hz output rate, delivering both fine-grained resolution and responsive real-time data.
Compact, Lightweight & Portable Design
Extremely lightweight (≤1.5 kg) with a compact POM housing (50 m pressure rating), making it easy to deploy from small boats, kayaks, or bridges for flexible field surveys.
Rugged Sensors & Environmental Compensation
Equipped with precision temperature, pressure, and attitude sensors, ensuring stable and accurate data collection even in dynamic, high-turbulence river conditions.
Large On-Board Storage & Versatile Connectivity
64 GB internal memory supports long survey missions, with RS-232/RS-422 interfaces for seamless data transfer and integration with field computers and hydrological software.
