pressure-tube anemometer
pres·sure-tube anemometer (prĕsh′ər-to͞ob′, -tyo͞ob′)n. Any of various pressure anemometers that measure wind speed by registering the displacement of liquid in a U-shaped tube that has one end exposed to the wind.pressure-tube anemometer
pressure-tube anemometer[′presh·ər ¦tüb ‚an·ə′mäm·əd·ər] (engineering) An anemometer which derives wind speed from measurements of the 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 difference, which is proportional to the square of the wind speed, is measured by a suitable manometer. |
