The Microflown is the worlds first and only MEMS technology based sensor that can measure the acoustic particle velocity. By measuring the temperature difference in the cross section of two extremely thin platinum wires placed in parallel, this extremely fast mass flow sensor is capable of monitoring the movement of air particles. Any sound field is described completely by both the (scalar) value sound pressure and the (vector) value acoustic particle velocity. Understandably, acoustic testing becomes much easier if both acoustic quantities can be measured. But the Microflown sensor platform can also be used to measure:

  • structural velocity
  • sound pressure
  • temperature


    Applications

    Microflown Technologies offers superior applications such as:
  • fast and broad banded vehicle interior noise source path contribution analysis
  • ( portable ) near field acoustic camera's
  • sound source triangulation techniques in the acoustic far field
  • in situ determination of acoustic properties of materials
  • non contact vibration measurements / modal analysis
  • acoustic surveillance of strategic objects
  • micropore leaktesting
