Full cross-stackduct measurement for superior accuracyUnaffected 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 temperatureInstalls in short runs - 2 dia. upstream, 1 dia. downstreamBuilt 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.
