Measurement / control system

• Flow range: 0.04 .. 20 ln/min (SLM) Mass flow units ln/min and SLM refer to normal operating conditions, i.e. 0°C (32°F) and 1013 mbar (14.7 psi)
• Accuracy: ± 2% RD for flow > 50% of max. capacity, ± (1% RD + 0.5% FS) on lower flows, Technical specifications are based on Air at maximum FS
• Repeatability: < 0.2% FS typical
• Operating pressure: 0 .. 10 bar(g) / 0 .. 150 psi(g)
• Pressure coefficient: 0.2% / bar typical at Air
• Pre-installed gases: Air, N2, O2, CO2, CO, N2O, Ar, CH4, C3H8 and C4H10
• Standard calibration gas: Air, other gases are converted using our Fluidat® conversion model which will introduce extra inaccuracy
• Rangeability: up to 1:100
• Response time (sensor): (t63%) 2 seconds
• Operating temperature: 0 .. 50°C (32 .. 122°F)
• Temperature coefficient: Zero: <0.1%FS/°C, Span: <0.2%RD/°C
• Leak integrity, outboard: < 1 x 10-9 mbar l/s He
• Attitude sensitivity: < 0.1% FS
