Whisper™ MCW–Series Low Pressure Drop Mass Flow Controllers
rapidly reach setpoints and maintain stable control of mass flow, volumetric flow, or pressure when there is little available system pressure, with pressure drops as low as 0.07 PSID.
Whisper™ MCW-Series performance (most products)
- Available full scale ranges: 0.5 SCCM to 1000 SLPM
- Steady state control range: 0.5% – 100% of full scale
- Standard accuracy calibration, NIST-traceable: ±0.75% of reading or ±0.1% of full scale, whichever is greater
- Optional high-accuracy calibration, NIST-traceable: ±0.6% of reading or ±0.1% of full scale, whichever is greater
- Repeatability: ±(0.2% of reading + 0.02% of full scale)
- Typical control response time: as low as 30 ms
- Warm-up time: <1 s
Whisper™ MCW-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: 60 PSIA
- Full scale pressure drop (range dependent): as low as 0.07 PSID
- Max differential pressure: 15 PSID
- Proof pressure: 80 PSIA
- User selectable reference conditions (defaults): 25°C & 1 ATM (STP) and 0°C & 1 ATM (NTP)
