an·e·mom·e·ter / ˌanəˈmämitər/ • n. an instrument for measuring the speed of the wind, or of any current of gas.DERIVATIVES: an·e·mom·e·try / -trē/ n.an·e·mo·met·ric / -məˈmetrik/ adj.

anemometer An instrument for measuring the speed of flow in a fluid. Meteorological anemometers measure wind speed. Most do so either from the rotation of a wind-driven turbine (‘rotating cups anemometer’) or from the wind pressure through a tube aligned by a vane to point into the wind (‘pressure-tube anemometer’).

anemometer An instrument for measuring wind speed, usually either from the rotation of a wind-driven turbine (‘rotating-cups anemometer’) or from the wind pressure through a tube aligned by a vane to point into the wind (‘pressure-tube anemometer’).

anemometer Instrument using pressure tubes or rotating cups, vanes, or propellers to measure the speed or force of the wind.
