[The] windmill anemometer [is] an anemometer in which a windmill is driven by the air stream, and its rotation is transmitted through gearing to dials or other recording mechanism. In some instruments, the rotating vanes and dials are in the same plane; i.e., both vertical, while in others the dial is horizontal. In the windmill type, the operation of air measurement involves readings of dials at the beginning and end of a measured period. Windmill instruments may be fitted with an extension handle, providing a form of remote control; used to measure air speed in an otherwise inaccessible spot.  3, record 4, English, - windmill%20anemometer

Another increasingly popular type of anemometer is the propeller anemometer. This anemometer is simply a very small two-or three-blade propeller, calibrated so that the revolutions per minute(rpm) corresponds to specific wind speeds. This anemometer is known as a "lift" device because it relies upon the rational lift caused by the wind on the propellers to measure the wind speed. By using two propellers held fixed at a perpendicular angle to each other, one can simultaneously measure the wind speed and direction using vector analysis. By including a third propeller positioned vertically relative to the other two, vertical wind movements also can be measured. It should be noted that the effect of variations in air density(due to temperature and/or pressure conditions) are accounted for differently in lift devices(for example, propeller anemometers) and drag devices(for example, cup anemometers).  4, record 6, English, - propeller%20anemometer

The ... propellor anemometer consists of a circular array of blades, usually not less than three, mounted at one end of a horizontal shaft; the blades are free to rotate in response to wind forces acting on them. A wind vane is attached to the opposite end of the shaft. The horizontal shaft is connected to a vertical shaft which, being mounted in bearings, turns as the varying wind direction acts on the vane.  2, record 6, English, - propeller%20anemometer
