VADCP

The Vertical Acoustic Doppler Current Profiler (Vertical ADCP) is designed for the high-accuracy measurement of water flow, level and velocity profile in open channels, rivers, streams, and irrigation channels.

The Vertical ADCP can be deployed as a self-contained instrument recording data for later use; as a real-time instrument for real-time measurements; or as a portable flow meter, with the option to move from station to station.

Key Features:

  • Teledyne RDI’s Broadband technology , which allows for small cells and/or short averaging/sampling intervals and highly accurate velocity data.
  • Range of 3–150 user-selectable velocity measurement cells, with cell sizes from 3cm–20cm and profiling range from 0.2m–5m.
  • Small transducer mounted to bottom of open channel allows for less flow disturbance.
  • Accurate acoustic water level sensor.
  • No calibration required, providing a cost-effective solution.
