The Airmar 150WX WeatherStation meets a growing need for real-time, site-specific weather information. For moving applications where true and apparent wind are different, the 150WX includes additional sensors such as a 10Hz GPS and solid-state compass. The 150WX features configurable RS422 and CAN BUS digital data outputs, providing unparalleled versatility for nearly all weather monitoring needs. The many new benefits of the 150WX include:
- Removable humidity sensor that is field serviceable
- IPX6 waterproof rating
- New power supply featuring a 50% reduction in current draw
- Wider operating voltage range of 9-40 VDC
- Adjustable, unfiltered wind data for monitoring maximum gust conditions
- Output via a single cable for power and data interface
- Low-cost, easy to install units either permanently or as a portable system
- Units can be installed on a standard pole with 1”-14 UNS or ¾” NPT threads

True wind is the flow of air caused by differences in atmospheric pressure. Apparent wind is the wind you would feel if you stuck your hand out of a moving vehicle. When you are stationary, apparent wind is equal to true wind. Airmar 150WX and 200WX WeatherStations measure both true and apparent wind, so they can be mounted on a moving platform while still gathering accurate data. When determining true wind, the WeatherStation uses its GPS determined location to correct the compass value from magnetic north to true north.
The 150WX includes an internal compass to determine and correct for the direction, so orientation is not important. That said, the compass can be influenced by local magnetic conditions. For maximum accuracy, the internal compass should be calibrated to local conditions after installation using the process described on Page 18 of the Owner's Guide (see Documents tab).
The humidity sensor is an optional feature. It can be purchased separately under the Accessories tab.
The GPS on the Airmar 150WX and 200WX WeatherStations includes WAAS and EGNOS for 10 ft (3m) accuracy.
In The News
Monitoring the weather isn’t just important for producing forecasts on TV news. It’s key to managing a whole host of other things, like expensive livestock, commercial fishing operations and even in the success of military warfare.
The folks at Airmar Technology Corporation know this firsthand, as weather monitoring products they make have been integral to the good outcomes of many projects over the years. Their current lineup of weather stations is full of high-quality sensors that deliver results, including the 110WX , 150WX and 200WX Ultrasonic WeatherStation Instruments.
These three options all boast the ability to gather basic weather parameters, but are ideally suited for different projects.Read More
When the wind blows over water, it creates waves and ripples. Those tend to bounce around and move things along with them like plants and nutrients. Scientists at the South Florida Water Management District (SFWMD) are investigating how cattails and other types of emergent aquatic vegetation impact nutrient transport in large constructed wetlands.
To test the hypothesis that emergent aquatic vegetation can reduce wind stress and, as a result, lower nutrient transport, researchers are conducting an experiment to quantify the effects that aquatic plants have on wind-generated stress in constructed wetlands. Results of the study could help improve management of the SFWMD’s stormwater treatment areas (STAs) and the reduction of nutrient concentrations, mainly phosphorus.Read More
Airmar’s business model is built entirely around transducers, mainly for boating and environmental applications. That meant it was only natural to base the WX Series WeatherStations around four transducers.
“The weather station uses transducers to measure wind ultrasonically,” said Irene Robb, Airmar product manager.
The four transducers are paired to send ultrasonic sound waves back and forth. Wind passes through a horizontal gap in the weather sensor housing and pushes the sound waves around.
The WX Series measures wind speed and direction based on delays or accelerations in sound wave transmission. Robb said Airmar engineers designed them to operate at a low frequency to minimize interferences.Read More
