NIST Certified Algorithm
OSI's Corrosive Gas Flow Meters utilize patented optical scintillation technology to deliver non-intrusive, maintenance-free flow measurement in harsh industrial environments including flare stacks, wet scrubbers, and thermal oxidizers. With ±2% accuracy and EPA 40 CFR Part 75 compliance, these sensors require no field calibration and are unaffected by corrosive gas compositions.

OSI flow meters use patented optical scintillation technology, transmitting a light beam across the stack or duct. The sensor analyzes fluctuations in light intensity caused by the moving gas to calculate velocity — entirely non-intrusive, with no probes or wetted components inserted into the corrosive gas stream.
