What instument is used to measure wind?

Answer 1

An anemometer is a device for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, meaning wind. The first known description of an anemometer was given by Leon Battista Alberti around 1450.

Wind direction is measured with wind (or weather) vanes or wind socks.

Answer 2

An Anemometer

• Wind speed is an important factor in a variety of fields, including maritime operations, civil engineering and weather forecasting. The device used to measure wind speed is called an anemometer. Quantitative measurements of wind speed were first made with anemometers as early as the 15th century. Modern weather services use adaptations of the anemometer that incorporate modern technologies like lasers or ultrasound sensors to increase measurement precision and repeatability. Two types of anemometers are used; namely cup anemometers and hot wire anemometers.

• Though basic in construction, the cup anemometer introduced in 1846 is considered an industry standard in measuring wind speed. Modern variants of this technology use three cups that spin around a vertical axis. The torque generated by the movement of wind is proportional to the wind speed. Cup anemometers must be calibrated because the torque also depends on the geometry of the cups used and the length of the arms they are attached to. Cup anemometers are relatively inexpensive and simple to construct, making them a popular project for science fairs.

• Hot wire anemometers exploit the electrical properties of metals to indirectly measure wind speed. The electrical conductivity of a metal wire is proportional to the temperature of the metal. A hot wire anemometer is essentially a fine metal wire that is heated above ambient temperatures. When wind blows, the wire is cooled, measurably reducing its conductivity. The degree to which the conductivity is reduced is proportional to the velocity of the wind. Hot wire anemometers are small and require electrical measurement equipment to use effectively.

The wind direction is measured with wind vanes or wind socks.

The wind speed is measured with an anemometer.

The tool that you use to measure wind speed is called an Anemometer.

Answer 3

The instrument used to measure wind speed is called an anemometer- it consists of three concave discs mounted on stalks that are attached to a central body, which then revolves on a pole. The speed at which this external part of the device turns is recorded electronically on a data chart, and is used to calculate the speed of the wind.

The instrument used to measure wind DIRECTION is the simple weather-vane. These have been in use at least since Mediaeval times and are often mounted on top of church spires or the tips of other publicly-used buildings.

Answer 4

The anemometer measures wind speed, a vane indicates direction. These are usually used on the ground, unless taken aloft on an aircraft or with weather balloon.
