Parameter to be measured:

Flow velocity (, discharge)

Method:

ultrasonic reflectogram cross-correlation

Equipment:

  • probe
  • display unit
  • wading rod

Advantages:

  • on-site discharge computation
  • powerful quality checking, configuration and data storage options
  • integrated depth measurement and sensor positioning indicator
  • convenient software with visualisation capabilities
  • USB (no serial port required)
  • rechargable via USB


Disadvantages:

  • heavy rods with coarse scale
  • sensor positioning indicator is difficult to read when adjusting sensor height or rod must be held without ground contact
  • test device showed signs of rainwater entering the display
  • built-in batteries, cannot be changed by user


What to watch out for:

  • cloudy waters, back pain (when adjusting depth of the probe free-hanging)
