The Handheld Anemometer, how does it work?
A handheld anemometer is basically a portable anemometer. It is a very reliable device that can easily help any weather watcher. Anemometers were first developed during the 15th century and have continuously been improvised ever since. The word “anemometer” is derived from the Greek word “anemos”, meaning wind.
The History of Anemometers
The first anemometers appeared in Italy and in Northern Europe before spreading to the Americas. They were very simple and ingeniously designed. It composed of a single flat disc which would shake in accordance to the winds motion. By looking at the inclination of the disc, the people could determine the degree of the wind pressure. By mid 19th century, more sophisticated anemometers were being used as cups were attached to the ends of a wind vane. When wind rose it would be caught by the cups making the vane turn. The number revolutions of the vane were recorded for readings. This kind of anemometer is still being used today. A similar version of this type spins like a wind mill (vertically) instead of the traditional vertical spinning.
Modern anemometers are very impressive devices that can give you accurate wind readings on an LCD display. They use not only the wind to make the readings but also the movement of sound waves, the detection of particles through laser beams, and the measurement of thermal energy.
What can an anemometer do?
An anemometer is a device to measure the speed of wind. It is used for meteorological purposes in weather stations. It can also measure the winds temperature, humidity and pressure.The five types of anemometers are:
- Hot Wire Anemometer – Sonic Anemometer – Laser Doppler Anemometer – Windmill Anemometer – Cup Anemometer
The Handheld Anemometer
A handheld anemometer or personal anemometer is a small device, usually only a few inches in length width, that is able to measure wind very accurately (within %5). Most handheld anemometers are capable of performing the following:
- Easily displays wind readings, – Can read wind chill and temperature in Fahrenheit and Celsius. – Measures wind speed (measures up to 100mph easily) in mph, km/h, m/s or Knots
Some personal anemometers have additional features to make the device more appealing. Some brands sell anemometers with a waterproof casing and are able to float on water. Others have included the Beufort Scale for the readings while others are even drop tested to make sure that the product will not easily break. Most handheld anemometers are built to not be affected by the changing directions of strong gusts of wind.
The Uses of a Handheld Anemometer
Many people can benefit from using a handheld anemometer. Since it is convenient to carry around, people who need to be aware of the weather will not have a difficult time doing it. Some people who may benefit by using a handheld anemometer are: engineers, serious kite flyers, wind surfers and climbers
Both professionals and amateurs can benefit from using a handheld anemometer. Since it is handy weather watchers can easily make their own weather forecasts confidently.
