Fits clean-gas mass-flow indication where you need an Aalborg GFM thermal mass flow meter with 0–5 V and 4–20 mA outputs.
Key advantages
- Thermal MFM — Low-cost thermal mass flow meter for clean gases (GFM)
- Ranges — From 0–10 sccm to 0–1000 slpm N2 (model dependent)
- Accuracy — ±1% FS (GFM 17/37/47); ±1.5% FS (GFM 57/67/77); repeatability ±0.25% of full scale
- Outputs — Linear 0–5 VDC and 4–20 mA; optional tiltable LCD
- Leak integrity — 1×10⁻⁹ sccs He max
Typical applications
- Clean gas mass-flow monitoring on lab and OEM gas panels.
- N2-referenced ranges from sccm to slpm class by GFM model.
- Analog 0–5 V / 4–20 mA loops with optional tiltable LCD.
Selection guide
- Model / range — From 0–10 sccm to 0–1000 slpm N2 (model dependent) — lock GFM 17/37/47 vs 57/67/77 class.
- Accuracy class — ±1% FS (GFM 17/37/47); ±1.5% FS (GFM 57/67/77)
- Max pressure — 1000 psig (69 bar) GFM 17/37/47; 500 psig GFM 57/67/77
- Wetted materials — Anodized aluminum/brass or 316 SS with FKM (optional Buna/EPR/FFKM)
- Elastomer — FKM std; Buna/EPR/FFKM options.
Common mistakes
- Ordering aluminum/brass body for gases that need 316 SS.
- Using GFM 17 accuracy (±1% FS) assumptions on GFM 57/67/77 (±1.5% FS).
- Exceeding 500 psig on the larger GFM 57/67/77 class.
When to RFQ / what to tell us
- Gas, calibrated range (sccm/slpm), inlet pressure.
- Aluminum-brass vs 316 SS; elastomer; LCD yes/no; quantity; ship-to.
