Acoustic Doppler Current Profiler for surface water discharge measurement

Categories: , Tags: , ,

OTT Qliner 2 – Doppler technology for mobile discharge measurement in rivers and channels.  The measurement is carried out using the classic verticals process. At the required vertical positions, the Qliner 2 measures both the vertical velocity distribution and the water depth. All measured data are transferred to the PDA via Bluetooth. After the measurement is complete, the discharge is available immediately. The Qliner 2 can be operated easily on cable ways, from bridges or from the edge.

  • Spot
  • Acoustic
  • Flow velocity and depth
  • Acoustic water profiling instrument for section by section discharge measurements in rivers and open channels up to 20 m water depth. Operated by PDA user software with Bluetooth data transmission. Low flow resistance and high boat stability.
  • ± 10 m/s
  • ± 1% of measured value ± 0.5 cm/s

Advantages

Reliable and precise ultrasound Doppler profiler

  • Intelligent evaluation algorithms
  • Discharge calculation according to internationally recognized standards (EN ISO 748)
  • GPS or bottom tracking data are not required
  • No measurement problems with a moving bottom
  • Ideal for small and medium-sized rivers
  • For measurements in case of flooding
  • No moving parts that could be blocked or jammed during measurement
  • Familiar measurement process, therefore easy to learn

Examples of Use

Discharge measurements for small and medium-sized river

  • Can be operated easily on cable ways, from bridges or from the edge.
