OMC-118 Ultrasonic Wind Speed
VDR / SVDR

The WindObserver II/65 provides one of the best accurate and cost-effective 2-axis wind measurement sensors. It combines the latest patented advances in ultrasonic technology together with Observator’s experience as the recognised world-leading supplier of all-weather ultrasonic wind sensors.

The elimination of moving parts, together with a rugged 316 stainless-steel construction, means that the WindObserver II/65 is virtually maintenance free and requires no calibration on site. An optional heated version keeps the unit free from ice and snow, providing continuous use even in the most extreme weather conditions. The flexible design ensures that the WindObserver II/65 can be configured by the user to their requirements, which may include analogue outputs, up to 10 Hz digital output, heating or sonic temperature. The WindowsTM based Anemcom ll 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 bi-directional link, which allows several units to be networked together and data to be logged on demand. The WindObserver ll/65, like all wind sensors supplied by Observator, is rigorously tested to internationally recognised standards and meets the stringent performance criteria specified by meteorological, naval and airport authorities and oil and utility companies around the world.
