Depth rating 1,000 / 3,000 / 6,000 m
Configurations Direct-reading
River ADCP — Discharge Measurement in Shallow, Turbulent Channels
River-type profilers are optimised for shallow water, complex flow and mobile operation: fast installation, strong anti-turbulence performance and stable discharge calculation for hydrographic gauging, urban river regulation and water resource monitoring, following ISO 748 discharge-measurement practice.
Muti-frequency river ADCP for small & shallow channels
River-ADCP-M9
Nine-beam muti-frequency head that keeps data valid in very shallow, high-turbulence flow — the recommended choice for streams under 10 m deep.

Bottom Track Range 40m
Velocity accuracy ±0.25%±2mm/s
Depth rating 50 m
Configurations Direct-reading
600 kHz five-beam river ADCP for medium channels

Velocity accuracy ±0.25%±2mm/s
Depth rating 50 m
Configurations Direct-reading
Horizontal ADCP — Permanent Side-Looking Discharge Stations
Horizontally mounted profilers for riverbanks, bridge piers and channel walls deliver continuous 24/7 discharge data without a boat or crew — the standard configuration for hydrological networks, flood warning and canal management.

600 kHz horizontal ADCP for unattended river stations
