The anemometer is an instrument for measuring the force and velocity of the wind.
This is done by the familiar weather-vane and the anemometer.
A little way beyond the screen, again, stood the wind-vane and anemometer.
"Why, to make one on the principle of the anemometer," replied Ralph.
Tom arose and went to the anemometer, or wind-registering instrument.
The Robinson anemometer was perhaps the greatest source of worry.
Hooke has been generally regarded as the first inventor of an anemometer, in 1662.
Wren also had an anemometer, but we have no description of it.
This anemometer should be fixed in an exposed situation, as high above ground as may be convenient for reading.
He read it through, and just handed it back to me, and went on monkeying with his anemometer.
An instrument that measures the speed of the wind or of another flowing fluid. The most basic type of anemometer consists of a series of cups mounted at the end of arms that rotate in the wind. The speed with which the cups rotate indicates the wind speed. In this form, the anemometer also indicates the direction of the wind. ◇ Other anemometers include the pressure-tube anemometer, which uses the pressure generated by the wind to measure its speed, and the hot-wire anemometer, which uses the rate at which heat from a hot wire is transferred to the surrounding air to measure wind speed.
