Anemometer is an apparatus for measuring the speed of wind. The commonest kind of anemometer is a kind of horizontal three-armed windmill, with a hollow hemispherical cup on the end of each arm. (See photo.).The pressure on the inside of a cup when it is back to wind overcomes the pressure on the rounded front of the cup on the opposite arm, and the cups revolve at rather more than two-fifths the speed of the wind. The mill moves a pointer round a graduated dial.See photo.).
