What are Wind Speed & Direction Instruments and How Do They Work?

Wind speed and direction are two of the many variables that meteorologists keep track of when observing the weather. The speed and direction of the wind can hold vital clues to understanding the weather play a major role in forecasting future conditions.  There are also many benefits to tracking wind speed and direction at your home.

Technological advances have significantly enhanced the accuracy of such devices. Various types of wind monitoring instruments may be used for measuring many different variables, including the direction and velocity of wind.

Cup Anemometer

The cup anemometer is one of the most popular types of wind monitoring devices, and the style that Maximum uses for its instruments. It is designed to measure the speed of wind. Outfitted with three or four small hemispheres or cups installed on arms, this device catches the wind. An electrical piece is used to record the number of revolutions that the cups make and then calculate the speed of the wind. These types of wind monitoring devices can prove to be beneficial in determining weather patterns and predicting approaching weather patterns. Cup anemometers are commonly used at weather stations and in other areas where it is important to measure wind speed, like airports.

Wind Vane

A wind vane is an instrument that shows you the direction of the wind. Wind vanes are simple in design—they consist of an arm with a fin.  This arm sits on a spindle which allows it to move on a horizontal plane with the wind. As the wind blows, the wind vane will let you know what direction the wind is coming from.

Wind Alarm

Wind alarms are another type of wind monitoring tool. Designed to give an indication to the user that the wind has reached a certain speed, this type of device may be configured by the user and can produce analog outputs. Alarms may contain a variety of different features, including adjustable time delays, the presence of two alarms, or a security code.

In choosing wind speed and direction instruments, many different factors will need to be taken into consideration. Along with having a rugged construction, the instrument should also feature an aerodynamic design. It is also important to ensure you choose a device that is known for its accuracy and repeatability. Depending upon your needs, it may also be necessary to procure a mounting accessory for the device that you choose.
