The important improvements of the version 6.0.14 are:

• Control valves
  The sound pressure level of resistance structures consisting of single-hole orifices was computed too low under critical conditions.
• Differential pressure transmitters
  The uncertainty of the discharge coefficient for orifices with a diameter ratio ß > 0.5 and Reynolds numbers between 10000 and 100000 were computed too high.
• Restriction orifice plates
  The computations of choked flow conditions and sound pressure level were revised.
• Pressure surge
  The input boundaries of pressures and of pressure differences were extended.
