4/12/2023 0 Comments Who invented anemometerSome types can be purchased and used at an affordable price, but others are best left to professionals (such as weather forecasters). In short, the anemometer is the reference device for measuring wind speed and pressure. Choose the ideal product according to your criteria. If you want to buy an anemometer and do your wind speed or pressure measurements, consider your measurement needs and the prices of the instruments on offer. John Thomas Romney Robinson, of Armagh Observatory. What matters is the accuracy of the wind data it provides! Do you know how your thermometer to measure temperature works? Not sure, and in fact, not so important. Cup anemometers A simple type of anemometer, invented (1846) by Dr. In the end, it does not matter how the anemometer works. Other anemometers of this type are ball, tube, and Pitot tube anemometers. ![]() It has evolved but its operating principle has remained the same. These devices for analysing wind pressure are less used than those for providing information on wind speed, but they are still used.Īmong the anemometers designed specifically to measure wind pressure but also capable of providing wind speed, we can mention the very first anemometer: the plate anemometer. Some of these weather instruments are based on measuring the force that the wind exerts on a plate that is held facing it, but others measure the wind pressure through a U-tube with a built-in pressure gauge. To measure wind speed and not as a weather forecast.Īnemometers that are more specialised in measuring wind pressure operate differently by design. A commonly used cup anemometer or Robinson’s anemometer measures horizontal wind speed and withstands extreme conditions.Īmong the instruments that also measure wind speed, the main ones are the propeller anemometer (easily used by home users), the windmill (or Byram) anemometer, the hot-wire anemometer, the ultrasonic anemometer, the bi-directional anemometer, the acoustic resonance anemometer, and the laser anemometer. None of them give the direction of the wind without a weather-vane.įirst, let's take the cup anemometer (Robinson's). Although their nature changes, their function remains the same: to measure wind speed and pressure secondarily, or vice versa. Today, there is not one anemometer, but many. The first recorded description of an anemometer was by Leon Battista Alberti in 1450. To obtain its direction, you need to combine the anemometer with a wind vane! The anemometer has no precisely known inventor. They only estimate the speed and pressure. In construction or industry, measuring wind speed is also important.īeware, however: contrary to what you might think, anemometers do not measure the direction of the wind. Are they the only ones to measure temperature or humidity? No, of course not! Other sectors such as air transport or shipping, which are very prone to bad weather and sudden changes in the weather, are also major users. Of course, the anemometer is not only used by the weather service. You may have already heard that the tide has turned, and therefore the weather will change. ![]() But why is that? The anemometer is a valuable piece of meteorological equipment for one simple reason: the wind is an essential parameter for predicting and understanding changes in weather conditions. A combination of wheels recorded the number of revolutions in a given timeframe.Īnemometers today employ a range of new technologies to measure wind speed and pressure, including sound waves, laser and Doppler technology, and electrical currents.Of course, wind speed is an important piece of information in weather forecasting, as is the measurement of temperature, for example. The hemispherical cup anemometer was invented by John Thomas Romney Robinson of Ireland in 1846. ![]() The revolutions of the Hemispherical Cup Anemometer are used to calculate the velocity of the wind. The most common anemometer, still widely used today, is the Hemispherical Cup Anemometer, which has three or four small hollow metal cups of hemispheres set to catch the wind and revolve around a vertical rod. This same anemometer was later “re-invented” many years later by Englishman Robert Hooke, who is often mistakenly credited as the anemometer’s inventor. His device consisted of a disk placed perpendicular to the direction of the wind that would spin due to the wind, the angle of inclination of the disk momentarily revealing its force. The earliest anemometer was designed by Italian inventor and architect Leon Battista Alberti in 1450. NPR 7120.5 Revision F Rollout Briefing (NASA Only)įor more than 550 years, mankind has had the ability to observe and measure the pressure and velocity of the wind through the use of the anemometer.Systems and Engineering Leadership Program (SELP).
