  OFS-2000C Optical Flow Sensor [Combustion Air]

 • Optimized for Primary and Secondary combustion air
 • Temperature and pressure-corrected flow or mass flow output.
 • Non-intrusive; nothing in flow path.
 • Measurement unaffected by distance, pressure, moisture & opacity.
 • 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.     

The OFS 2000C model is enhanced with temperature and pressure sensors to provide data for mass flow measurement. This latest development of our renowned air flow sensor offers operators more accurate control* of the combustion process resulting in increased efficiency, fuel cost savings and reduction of greenhouse gas emissions.
