what are the main purpose of the anemometer?

the anemometer is an instrument for measuring air velocity. Its sort is more, the most commonly used for the wind cup anemometer, meteorological offices and stations, it is composed of three to 120 & deg; Fixed on the bracket of the parabolic taper part of induction, the empty cup empty cup of concave forward a direction. The induction part installed on a vertical axis, in under the action of wind, the wind cup axis is proportional to the speed of the wind speed to rotate. Another rotating anemometer is propeller type anemometer, composed by a 3 leaf or four propellers induction part, install it in a bellwether of the front, to make it at any time on the wind. Blade around the horizontal axis is proportional to the speed of the wind speed to rotate.

anemometer application is very extensive, can apply, in all fields, are widely used in electric power, steel, petrochemical, energy saving etc, and other applications in the Beijing Olympic Games, sailing, rowing race, the wild shooting games and so on all need anemometer is measured. Now the anemometer is more advanced, in addition to measure wind speed at the same time can also measure air temperature, air velocity. There are a lot of industry needs to use anemometer, it is recommended to use the industry: sea fishing industry, all kinds of fan manufacturing, need convulsions of exhaust system, etc.

the main purpose of the anemometer:

1, the measurement of average flow velocity and direction.

2, measure to the pulsation of the flow velocity and its frequency spectrum.

3, measurement of turbulent Reynolds stress and the speed of the two correlation and time correlation.

4, measurement of wall shear stress ( Is usually used with wall is placed flush hot film probe, principle similar to hot line speed) 。

5, measure fluid temperature ( Probe resistance is measured in advance along with the change of fluid temperature curve, and then according to the measured resistance can determine the temperature probe.

in addition also developed many professional purposes.
