Alicat Scientific MW | Whisper Low Pressure Drop Mass Flow Meter | 0.5 SCCM-1,000 SLPM, 0.07 PSID drop
The Alicat Scientific Whisper MW measures gas flow with pressure drop as low as 0.07 PSID, across full scales of 0.5 SCCM to 1,000 SLPM and up to 60 PSIA. Accuracy is ±0.6% of reading with repeatability of ±(0.1% of reading + 0.02% FS). It fits systems with limited source pressure, such as gravity-fed or vented lines.
