Emissions / Air Flow Sensor

OSI OFS-2000F

Features

  • Specifically designed for Flares stack and reports flow velocities from 0.03 - 170 m/sec with a ± 2% accuracy.
  • Accurate flow readings.
  • Easy installation and optical alignment.
  • Long-term reliability: no blowers or moving parts
  • Ultra-low maintenance design.
  • Rugged; designed for harsh environments.
  • Built in continuous self-test diagnostics.
  • Measurement unaffected by path length & media pressure, moisture & opacity.
  • No flow media high temperature limits.
  • Compliant with EPA 40CFR Parts 60 & 75.
