Full cross-stackduct measurement for superior accuracy • Unaffected by distance & pressure, moisture or opacity. • Non-intrusive; nothing in flow 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 - 247365. • Rugged ultra-low maintenance design for harsh environments. Our original patented and still unequalled stackduct flow velocity sensor for Continuous Emissions Monitoring Systems (CEMS). The OFS uses EPA - approved Method 14 optical scintillation technology. Optical scintillation technique uses advanced Digital Signal Processing (DSP) electronics to measure the movement of turbulence found in a gaseous flow stream to provide highly accurate, path-averaged air velocity measurements. OFS accuracy has been proven by the U.S. National Institute of Standards (NIST) and at customer sites world-wide.
