Uses and Benefits of an Anemometer
Anemometers are used to measure wind readings. These beneficial instruments take their name from the Greek word for wind “anemos” and have been around since the 15th century and were originally from Europe, specifically the northern part of the continent and Italy. Eventually, the tool traveled to the Americas. The early anemometers were rather simplistic. They were flat discs that moved with the flow of the wind. The direction and wind pressure were determined by looking at the position of the disc.
The anemometer design was altered in the 19th century. This incarnation was a wind vane with sporting cups attached to it. The wind blew into the cups to move the wind vane. How the wind vane moved determined the wind pressure. This type of anemometer still exists, but a windmill on the weathervane has replaced the cups.
Current anemometers are easier to use than their ancient counterparts and also much more convenient and versatile. There are many types of handheld anemometers available that make taking wind readings easy and convenient. Additionally, current anemometers are much more accurate than the previous forms of the tool. Modern versions provide wind and sound wave readings on a LCD screen. Laser beams are used to measure thermal energy and detect particulates.
Anemometers are usually divided into two classes: one class is designed for measuring wind speed, and the other is designed to measure wind pressure. However, many anemometers will typically provide information for both. Weather stations use modern anemometers to gauge wind and how it relates to humidity, temperature and pressure. There are also anemometers available that help with other meteorological findings. The five basic types of anemometers available for are: Sonic, windmill, hotwire, cup and hotwire. Each uses their own particular method for providing measurements and testing the wind speed, and one may be more beneficial than the other in certain situations.
A handheld anemometer is typically very compact, measuring only a few inches, and extremely useful for gathering wind information. The readings include the speed of the wind in different measurements (mph, m/s, km/h or Knots), wind chill and temperature. Sudden changes in the wind speed or direction, as well as wind current, do not usually interfere with the accuracy of handheld anemometer readings.
Along with the upgrades in accuracy and design, you can find anemometers with special features. For example, you can find them with casings that are waterproof or a more accurate Beaufort scale. Some models are also drop tested to determine how resilient they are.
Anyone can benefit from using an anemometer. You do not necessarily have to work in the weather field. Engineers can benefit from using predicting wind and weather with anemometers. Hobbyists who spend time outdoors will also enjoy using anemometers. For example, you should have accurate information about the wind and weather before you rock climb, wind surf or fly a kite.
