American Nuclear Society Standard for Determining Meteorological Information at Power Plants.
Wind speed is sensed by a lightweight, carbon fiber thermoplastic (CFT), helicoid propeller. The wind direction sensor is a lightweight, balanced vane. The instrument body is UV stabilized plastic with stainless steel and anodized aluminum fittings. The instrument mounts on standard 1 inch pipe. The Wind Monitor-AQ is available with two additional output signal options:Model 05305V offers calibrated voltage outputs. Model 05305L provides 4-20 mA current signals.
