What is anemometer?

Anemometer is a meteorological device that is used to measure wind speed. Anemometers come in various forms, but the simplest type is Anemometer . The Anemometer Cup consists of a vertical pole with four horizontal arms connected to the top. The cups are attached to the end of four arms and the wind causes the cups to rotate the arms around the central pole. The cup anemometer is susceptible to friction, which makes it less accurate than the more advanced version. A person using one can calculate the wind speed by multiplying the cup revolutions per minute by the circuit of the circle that the cups create. The product will be close to the wind speed per minute.

The wind anemometer is similar to its namesake, a windmill, in that it must be parallel to the wind direction to function properly. The wind blade, connected to the tailnemometer, is pushed around until the propeller is facing the wind. The wind then turns the propeller that rotates through the mechanism that calculates the wind speed.

A thermoelectric anemometer uses a very thin wire that is heated to a temperature that is higher than the ambient air temperature. The wind cools the wire and the electronics in the body calculate the wind speed based on electrical wire resistance. Anemometers of this type are rather fine tools, but are also quite accurate in determining wind speed.

Laser doppler and ultrasonic anemometers are high-tech and very accurate. laser doppler anemometers measures wind speed by detecting how much light from the laser beam has been reflected from moving air particles. ultrasonic anemometers Determine the speed of winding waves between a pair of converters and determining how their speed is affected. Because ultrasonic anemometers are able to measure wind speed and wind direction, they are popular for use on ships, aircraft, meteorologiCosts of meteorologists and scientific wind turbines.
