Optical Scientific, Inc. (OSI) designs and builds advanced optical instruments to measure air flow, turbulence, precipitation and visibility for scientific, aviation, meteorological, and industrial applications. Their systems are in use worldwide in hydrocarbon refineries, smelters, airports and seaborne vessels, as well as commercial and industrial sites.
Clients include the National Weather Service (NWS), the US Federal Aviation Administration (FAA), the Massachusetts Institute of Technology (MIT), the National Aeronautics and Space Administration (NASA), the US Armed Forces, and the US Geological Survey (USGS).
Optical Flow Sensors For Air/Gas Velocity Measurements
LOA (Long-baseline Optical Anemometer) Originally developed for large-scale tracking of air movement and turbulence up to a distance of 10km. Useful for fence line, airport runway vortex monitoring, LOA can also be found at work in aluminum smelting operations. The proven tracking techniques of the LOA are applied in the more compact OFS 2000 developed for industrial applications.
OFS 2000 uses optical scintillation-based, non-contacting, cross-stack flow measurement incorporating advanced digital signal processing (DSP) to accurately calculate air velocity or mass flow. This measurement principle gives constant calibration-free operation 27/7/365.
Originally designed to facilitate the measurement of greenhouse gas emissions, additional refinements have enabled them to be used in chemical processes, gas and oil refineries, mining operations, steel mills, incinerators, and electrical power plants.
OFS 2000 series sensors meet or exceed regulations set by the Environmental Protection Agency (EPA) and South Coast Air Quality Management District (SCAQMD).
Automated Weather Observation Systems For Adverse Environments
MAWOS (Modular Automated Weather Observation Systems) are used for continuous weather reporting in aviation applications large and small.
A flexible, robust, and reliable system, the MAWOS is designed to meet Automated Weather Observation System (AWOS) specifications set by the FAA and Canadian Aviation Regulations (CAR).
Used by the World Meteorological Organization (WMO), National Weather Service (NWS) and meteorological departments worldwide, OSI's long-established OWI-432 optical sensor is a key component in the MAWOS.
Automated voice broadcast in French and English is available on mobile or landline phone, and Very High Frequency (VHF) aviation band. Systems can also report via the Internet.
Low Power (LPAWOS) battery and solar powered versions are available.
HazMet is a compact portable MAWOS designed for fast deployment in high-risk environments where hazardous materials or air pollutants may be present.
This basic battery-powered system reports wind, temperature, relative humidity (RH), barometric pressure, and can be configured for more.
The HazMet has a wide range of features, including:
- EPA Cameo / Aloha data output
- Spread spectrum radio
- Built-in GPS with electronic compass, self-diagnostics and testing
- Battery or AC powered. Solar power options available
- Small, lightweight and rugged
- Deploys in less than five minutes
- Operates unattended with virtually no maintenance
