WindObserver II Ultrasonic Anemometer 
 |
| WindObserver II |
The WindObserver II, manufactured by Gill Instruments, provides the best solution on the market for reliable, accurate, and cost-effective wind speed and directional measurement. The elimination of moving parts together with a rugged stainless steel construction means that WindObserver II is virtually maintenance-free and requires no calibration on site. The heated head keeps the unit free from ice and snow, providing continuous use even in the most extreme weather conditions.
A new flexible design ensures that the WindObserver II can be configured by the user to their exact requirements, which may include analogue outputs, 10 Hz output, heating, or sonic temperature.
The Windows™-based WindCom communications package allows the user to operate the anemometer in various modes, permitting the measurement of U & V vectors or wind speed and direction. Communication is via an RS422 bidirectional link, which allows several units to be networked together and data to be logged on demand. The WindObserver II has been rigorously tested to internationally recognised standards and meets the stringent performance criteria specified by airport, marine, oil, production, meteorological, and utility organizations around the world.
