– 20mm/s to 3200mm/s in one direction (parameter setting)
– Bidirectional flow capacity (parameter setting)
Velocity Accuracy: ±2% of measured velocity
Velocity Resolution: 1mm/s

Depth Range: 20mm to 2.0m/5.0m*
* Range is above sensor and up to 2000mm in water with heavy sediment and up to 5000mm in water with medium sediment.
Depth Accuracy: Typical ± 1%
