OFS-2000F Optical Flow Sensor [Flare Gas Flow Monitor]

• Measurement Technique Optical scintillation
• Dynamic Range 0.03 to 100 m/sec, bidirectional
• Accuracy (absolute) +/- 0.01 m/sec basic -or- <2% of reading, whichever is greater
• Repeatability (relative) +/- 0.01 m/sec basic -or- <1% of reading, whichever is greater
• Dust Intrusion IP65

Full cross-stackduct measurement for superior accuracy • Unaffected by distance & pressure, moisture or opacity. • Conforms to EPA 40 C.F.R. Part 60 Subpart Ja. • Non-intrusive; nothing in flow path. • No flow media high temperature limits. • No calibration necessary. • Accurate at low velocity and ambient temperature • Installs in short runs - 2 dia. upstream, 1 dia. downstream • Built in continuous self-test diagnostics. Whatever you call it: Flare Gas Sensor, Flow Monitor, or Flare Analyzer, OFS 2000F is specially developed for refinery flare stack applications where increased velocity scale, wider temperature range, and quick response time are necessary. OSI's optical scintillation technology provides the most accurate, path-averaged air velocity measurements of any flare gas sensor. It's superiority has bee proven again and again, in flare, air-assisted flare, and SRU (Sulfur Recovery Unit) installations world-wide.
