Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment

Instrument in which the excess of pressure and suction associated with the action of the wind on tube openings are combined to operate the float of a manometer.


[A] pressure-tube anemometer [is] an anemometer which derives wind speed from measurements of dynamic wind pressures. Wind blowing into a tube develops a pressure greater than the static pressure, while wind blowing across a tube develops a pressure less than the static. This pressure differential, which is proportional to the square of the wind speed, is measured by a suitable manometer. [e.g.:] anemo-biagraph, Dines anemometer, Pitot tube.


  • Stations, instruments et équipements météorologiques

Instrument dans lequel la surpression et l'aspiration liées à l'action du vent sur les ouvertures du tube sont combinées pour actionner le flotteur d'un manomètre.


Campo(s) temático(s)
  • Estaciones, instrumentos y equipos meteorológicos

Instrumento en el que el incremento de la presión y la succión asociados a la acción del viento sobre los orificios del tubo se combinan para accionar el flotador de un manómetro.
