Measurement / control System    

• Flow range: QA - 200 In/min (SLM) Mass flow units In/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, OZ COZ CO, N20, Ar, CH4, C3H8 and C4H10
• Standard calibration gas: Air, other gases are converted using our Fluidat* conversion model which will introduce extra inaccuracy
• Rangeablllty: 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: tested < 2 x 10-9 mbar l/s He
• Attitude sensitivity: < 0,1 % FS
