Description

MCQ-Series High Pressure Gas Mass Flow Controllers

 rapidly reach setpoints and maintain stable control of mass flow, volumetric flow, or pressure for operating pressures up to 320 PSIA.

MCQ-Series performance

  • Available full scale ranges: 10 SCCM to 3000 SLPM
  • Steady state control range: 0.5% – 100% of full scale
  • Standard accuracy calibration, NIST–traceable: ±0.6% of reading or ±0.1% of full scale, whichever is greater
  • Repeatability: ±0.1% of full scale
  • Typical control response time: as low as 100 ms
  • Warm-up time: <1 s

MCQ-Series operating conditions

  • Compatible gases: 98 pre–loaded selectable gas calibrations; additional mixtures definable with COMPOSER™
  • Operating temperature: –10°C to +60°C
  • Full scale operating pressure: 320 PSIA
  • Max differential pressure: 75 PSID
  • Proof pressure: 400 PSIA
  • User selectable reference conditions (defaults): 25°C & 1 ATM (STP) and 0°C & 1 ATM (NTP)
