Ultrasonic Velocity Profiler (UVP) measures liquid flows velocity as a function of distance, using a pulsed-Doppler based method. It uses the following principles :

  • Pulsed emission of ultrasound signals
  • Echography : echo reception as a funtion of time
  • Detection of the Doppler shift frequency

    UVP instrument is made of 3 main parts :

  • Transducer : transformation of electrical signals in ultrasound acoustic signals, see 'Transducers'
  • Measuring unit : signal processing and digitalization, see 'Hardware'
  • User interface : data analysis and storage, see 'Software'
