- Features
1. 20 coordinate points to describe the river’s shape of cross section.
2. One instrument can measure the velocity, depth and conductivity at same time.
3. Velocity Range : 0.02mm/s to 10m/s bi-directional, accuracy is 1%.
4. Depth Range: 0 to 10m
5. Measure velocity in both forward flow and back flow.
6. Depth is measured by both the pressure sensor and ultrasonic level sensor principles.
7. With coordinate correction and pressure compensation function.
8. IP68 Epoxy-sealed body design, long time under water.
9. RS485/MODBUS output, can contact computer directly.
