Sonic orifice or sonic nozzle system

Our dilution system is based on laser calibrated orifice technology. This technology allows greater flexibility in term of dilution ratio and greater precision compared to traditional mass flow type system. In the sonic flow mode, the flow through the orifice is only a function of the inlet pressure. No influence from ambient or outlet pressure. When combined with our ultra stable temperature compensated electronics pressure controller (EPC), this technology offers unsurpassed performance.

Use pressure to flow caracteristics of sonic orifice to control dilution ratio

  • Pressure to flow function is linear in sonic mode
  • High accuracy
  • No influence from back pressure
  • Compatible with corrosive gases
  • High leak and sample integrity
