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.
