A vane anemometer thus combines a propeller and a tail on the same axis to obtain accurate and precise wind speed and direction measurements from the same instrument. The speed of the fan is measured by a rev counter and converted to a windspeed by an electronic chip.
An anemometer is a device for measuring the wind speed, and is one instrument used in a weather station. C. Wind Speed. yes. An anemometer is a weather instrument with three cups attached to a freely spining rod that measures wind speed.An instrument for measuring the speed of the wind, or of any current of gas.nemometers can be divided into two classes: those that measure the wind's speed, and those that measure the wind's pressu â¦ re; but as there is a close connection between the pressure and the speed, an anemometer designed for one will give information about both.
