OFS-2000R for Industrial Steam Lines

OFS 2000R Brochure

The FS-2000R is developed to ensure that refinery operators meet EPA MACT RSR 40 CFR 63.670 requirements for steam-assisted flare stacks.

The OFS 2000R can see through steam in the vapour phase, delivering accurate, quick-responding control signals, which enables the operator to match the steam flow exactly to the flare output and prevent oversteaming or overaeration, and maximise combustion efficiency. OFS 2000R has a 5000/1 turndown ratio, no pressure drop and is easily mounted on a steam line.

  • Full cross-stack/duct measurement for superior accuracy.
  • Unaffected by distance & pressure, moisture or opacity.
  • Non-intrusive; nothing inflow path.
  • No flow media high-temperature limits.
  • No calibration necessary.
  • Built in continuous self-test diagnostics.
  • Easy installation and alignment.
  • No moving parts: operates unattended – 24/7/365.
  • Rugged ultra-low maintenance design for harsh environments
