For drift-free air flow measurements across traffic tunnels; WSS-300 calculates true average speed of air movement, and detects smoke. Equipped with Automatic Gain Control (AGC) to compensate for opacity variations caused by particulates, smoke, or suspended moisture, the WSS-300 uses patented optical scintillation technology coupled with advanced Digital Signal Processing (DSP) electronics to "see" and deliver highly accurate, path-averaged air flow measurements superior to anything on the market today.

• Measurement TechniqueOptical scintillation
• Velocity Range0.1 to 40 m/s velocity
• Path Length0.3 to 3 meters (1 - 10 ft. Contact OSI for other lengths)
• Data Output4-20mA and/or RS-232 ASCII serial I/O
• Dust IntrusionIP65

Our customer asked for an economical, and precisely accurate instrument to measure levels in industrial storage tank, large commerical process bins, and agricultural silos - and we delivered. Taking our expertise in optical sensing instruments, we developed the LLM-100 to provide superior measurement capacity at low cost. At the same time, we designed the controller to support up to four separate sensors. As all our sensors, it is easy to install, needs almost no maintenance, and is equipped with continuous self-diagnostics.
