Dwyer GFM-1103 | Gas Mass Flow Meter | 0-50 mL/min N2, 1/4" compression
Sized for 0-50 mL/min of flow, referenced to nitrogen at 21°C, 760 mm Hg, the Dwyer GFM-1103 gas mass flow meter connects through a 1/4" compression fitting. A restrictor element and straight-tube sensor feed the GFM-1103's tiltable 3-1/2 digit LCD; a NIST-traceable certificate comes with it.
- GFM-1103 response: 2 s to within ±2% of flow
- GFM-1103 pressure limit: 1000 psig (68.9 bar)
- Wetted parts of the GFM-1103: anodized aluminium, brass and 316 SS with fluoroelastomer O-rings
- Operates at 0 to 50°C from ±12 VDC (GFM-1103)
- 0-5 VDC and 4-20 mA outputs; usable with the Series GFT Flow Totalizer (GFM-1103)
- GFM-1103 accuracy ±1% FS (5 to 25°C, 5 to 60 psia), repeatability ±0.25% FS
