Deep Learning Function
| Water Flow Detection | 1. Water level detection supports water level gauge mode and virtual water level gauge mode. Measurement distance ≤ 100 m, water level measurement range 0 to 40 m, resolution 1 cm, detection accuracy ±2 cm. 2. Supports flow velocity detection, with a measurement range of 0.35 to 10 m/s, resolution 0.01 m/s, and measurement error: for flow velocity > 1 m/s, the relative error is 10% to 20%; for flow velocity < 1 m/s, the absolute error is ±0.1 m/s. |
