A World Leader in Optical Sensor design
OSI develops the worlds most advanced optical sensors for monitoring Precipitation, Present Weather, Air/Gas Flow, Crosswinds & Atmospheric Turbulence. Our sensors are often used in critical areas of infrastructure. and utilized for environmental monitoring, compliance & process control. OSI sensors are designed to work reliably for unattended field operations - 24 hours a day, 7 days a week.
APG All Precipitation Gauge APG-815
OSI’s APG-815-DS uses proven optical scintillation technology and offers many performance and maintenance advantages over traditional tipping bucket and weighing type rain gauges.
OFS-2000 Optical Flow Sensor
OSi's patented Optical Flow Sensor (OFS) measurement is a instantaneous cross stack line average. OFS measures velocities from .03 -170 M/sec with a 2% +/- accuracy. OFS measurement technique has zero effect from changes in temperature, pressure, humidity, or gas composition. and is a non-intrusive measurement.
