Wind Gauges

Wind gauges are instruments used to determine and record the direction and velocity of wind. An anemometer is a computerized wind gauge. Wind gauges are of two types, i.e. those that measure the speed of the wind, and those that measure the wind pressure. Since there is close connection between speed and pressure, an anemometer can give information on both if specifically designed. Wind gauges are available in different sizes, including pocket-sized and portable wind gauges.

Wind speed is displayed in different choices, and in some models three to six modes of wind speed is displayed. Temperature and humidity are recorded and updated frequently. It can also display temperature and wind-chill factor. Some portable wind gauges feature a data hold function that freezes the measurement.

Other models feature an ultra-sensitive vane impeller. This responds to wind speeds under 1 mph and up to 135 mph. Clear LCD display shows current wind speed along with average wind speed, and maximum wind gusts. Most portable wind gauges are waterproof and housed in a protective case.

The wind gauge must be installed in a location that allows wind to flow freely without any structural obstruction. It is placed at 33 feet above ground with no obstructions. Installation can be expensive and difficult. Wind measurements taken at 23 feet are also accurate. Any obstructions like trees, nearby houses and buildings, etc. have the ability to affect wind gauge readings. Another important factor is vertical mounting of the mast and adjusting the wind direction indicator to the north for reliable wind direction readings. A magnetic compass can locate the north. Check for any height restrictions that are set by local authorities and homeowners associations. High winds and ice or snow can add stress on the assembly, so it is better to ensure that the installation is strong and can withstand any drastic temperature changes as well as stormy wind conditions.
