OFS-2000 Optical Flow Sensor

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.
