Overview
HydroFlow measures water velocity through the water column and tracks the bed, so you can calculate discharge across a river section in one crossing. The 600 kHz model reaches deeper water (up to 90 m profiling); the 1200 kHz model gives finer cells in shallow rivers and canals. It can be towed on a small trimaran or mounted on a HydroBoat USV.
Key features

- Bottom tracking with depth up to 120 m (600 kHz)
- Internal compass, tilt and temperature sensors
- 16 GB internal memory
- Trimaran float or USV mounting
