Critical Flow Controller

This model builds on the functions of Model I with the addition of differential pressure transducers for measuring and presenting pressure at P1 and P2 and P3.

Key features are:

  • Generous flow path which minimizes loss of flow and helps attaining the critical flow condition (P3/P2 ratio)
  • Flow control valve
  • Measurement of P1 and critical flow (P3/P2 ratio)
  • Resettable counter for actuations
  • 3.5″ TFT touch screen for control and presentation of measured values, suitable to operate with or without gloves
  • Port for external printer (list of dose #, P1 and ratio)
  • Input to actuate from optional handheld or foot switch
