Automatic Weather Station Prices and Options

Installation costs depend on the system type, site conditions, and required infrastructure. The FAA-certified AWOS-AV requires professional installation and is included in the $100,000–$500,000 system price range. Modular and portable systems like the MAWOS and OWI-432 are simpler to deploy — the OWI-432 clamps to standard pipe without cement pads, and the HazMet-100 sets up in under 5 minutes without tools, reducing installation labor significantly.

OSI offers four main categories: the AWOS-AV (FAA-certified aviation station), the MAWOS (modular automated station for aviation, DOT, and military), the OWI-432 WIVIS (compact modular station for remote and research use), and the HazMet-100 (rapid-deploy portable station for emergency response and hazmat operations).

The AWOS-AV is OSI's FAA-certified automated weather observing system, fully compliant with FAR 91.171, FAR 91.175, and ICAO standards. The MAWOS and OWI-432 WIVIS are non-FAA certified but comply with NWS and WMO standards, making them suitable for non-regulated aviation and other critical applications.

OSI weather stations measure temperature, relative humidity, wind speed and direction, barometric pressure, visibility, precipitation type and rate, dew point, and present weather conditions. The AWOS-AV additionally provides dual altimeter settings via dual-pressure sensors. The HazMet-100 focuses on atmospheric parameters critical for hazmat dispersion modeling.

Yes. The MAWOS and OWI-432 WIVIS support solar and battery power in addition to standard AC, enabling deployment in remote, unattended locations. The OWI-432 WIVIS has been proven in extreme environments from Antarctica to tropical rain forests. The HazMet-100 is also low-power and battery/solar compatible for rapid portable deployment.

OSI's optical scintillation-based sensors require virtually no scheduled maintenance. There are no moving parts, no scheduled cleaning of optics, and the systems are insensitive to dirt buildup. Built-in continuous self-test and self-diagnostics monitor performance automatically, and MTBF exceeds 80,000 hours, minimizing service interruptions and long-term operating costs.
