Surprisingly cheap anemometers can be purchased from some of the major vendors on the market. The difference between the measured pressures allows the wind speed to be determined. The compression anemometer is based on a Pitot tube and consists of two small tubes, one of which has a front hole (for measuring dynamic pressure) and a side hole (for measuring static pressure), and the other has only a side hole. Its rotation is proportional to the wind speed and can be easily recorded In a magnetic anemometer, this spin activates a microgenerator to help with accuracy. The rotary anemometer is equipped with a cup (Robinson) or a propeller connected to the central shaft. The thrust is formed by a hollow and light sphere (Daloz) or paddle (Wild) whose position relative to the suspension point changes with the wind, which is measured in a quadrant. Its use is very practical, the data you provide is very useful, and as it is not very expensive, anyone can enjoy its benefits, making this measuring instrument the basis of the daily and professional life of many people. Of course, some are more accurate than others. All provide a measure of the velocity of gaseous fluids. is for wind speed calculations.Īlthough other types provide major changes to the original model and images, their functionality has not changed. The physical characteristics of the anemometer vary greatly due to its appearance, but as the most used rotation, you should know that it has a blade on its body, a few popsicles or cups at the end, and a fan-like torso. The unit of measurement is km / h or m / s. To measure the horizontal wind speed, the most widely used instrument is the cup anemometer, in which the rotation of the cups is proportional to the wind speed. The laps it makes are read by a counter or recorded on a paper band if it is an anemograph. When the wind 'collides' with the windlass, it rotates. The most used are the so-called windlass. Thanks to these meteorological instruments we can know the speed of the wind. That is why it is very suitable for nautical activities. On the other hand, an anemometer allows us to immediately measure the maximum speed of a gust of wind. An anemometer measures instantaneous wind speed, but bursts can distort measurement results, so the most accurate measurement is the average of measurements taken every 10 minutes.
