Wind Indicators

Wind indicators provide a readily visible indication of wind direction and, depending on design and installation, a general indication of wind conditions. They support operational awareness at industrial facilities, storage yards, process plants, tank farms, airports, and locations where wind direction can influence emergency response or the movement of airborne contaminants. They are visual aids and should not be treated as precision meteorological instruments unless the specific model is designed and certified for that purpose.

A typical system uses a fabric indicator or equivalent directional element mounted on a support structure. The element aligns with the prevailing airflow, giving personnel a quick reference to wind direction. Some installations include a stand, protective cage, lighting, or weather-resistant construction to improve visibility and durability. The height and placement of the installation should allow the indicator to respond to airflow without being unduly affected by nearby structures, exhausts, turbulence, or obstructions.
