![]() ![]() How Does Anemometer Measure Work?Īn anemometer is a device used to measure wind speed. It doesn’t have any rotating parts, so it’s more durable.Ī few drawbacks are pitot tube anemometers need to be pointed directly at the source to get accurate results. Pitot tube anemometer is also very responsive and easy to install. It can deal with high temperatures and speed. The wind speed is then calculated based on the pressure difference between the inside and outside of the tube. As the wind blows, the air is forced into the tube, and the pressure is measured. Pitot Tube Anemometers:Ī Pitot tube anemometer consists of a tube with a small opening at the end. Also, rapid fluctuations in the temperature are not suitable for this anemometer. They have small sensors, and they last longer than others.īut big elements in the air can harm it. Hot wire anemometers are very accurate and precise. The wind speed is then calculated based on the cooling rate. Hot Wire Anemometer:Ī hot wire anemometer consists of a thin wire that is electrically heated. This device is not that good with the low measurement at all. The icing effect can also manipulate the readings in cold weather. High winds can damage cup anemometers, requiring regular maintenance and calibration. You can use them in various settings, including weather stations, airports, and wind farms. It doesn’t need to point directly at the source. The wind speed is then calculated based on the number of rotations per minute.Ĭup anemometers are very accurate and precise. ![]() As the wind blows, the cups rotate, and the shaft turns. It consists of four cups mounted on a horizontal shaft. The cup anemometer is the most common type of anemometer. They require regular calibration and can damage by high winds as cup anemometers. It has a few drawbacks also, vane anemometers must point towards the source to get an accurate result. They are relatively low maintenance and can handle higher wind speeds. Vane anemometers are very durable and can withstand high winds. The wind speed is then calculated based on the number of rotations per minute. As the wind blows, the vanes rotate the wheel. Vane Anemometer:Ī vane anemometer consists of a large rotating wheel with vanes attached. Every type of anemometer measures wind speed by quantifying the wind’s force on a moving object. There are many different types of an Anemometer, each with its advantages and disadvantages. It can also be a hazard, so it is important to be able to measure wind speed. Wind speed is important in many activities, including construction, flying kites, and sailing. The number of rotations per minute is then recorded to calculate the wind speed.Īnemometers are used in various settings, including weather stations and airports. When wind pushes into the anemometer, it causes the cups to rotate. The faster the wind speed, the faster the cups spin. The most common type of anemometer is the cup anemometer, which consists of three or four cups that spin in the wind. There are many different types of anemometers, but they all work by measuring the force of the wind on a moving object. An anemometer is a tool that gauges wind speed. ![]()
