Anemometers may be divided into two classes, (1) those that measure the velocity, (2) those that measure the pressure of the wind, but ... a suitable anemometer of either class will give information about both these quantities. ... Anemometers which measure the pressure may be divided into the plate and tube classes, but the former term must be taken as including a good many miscellaneous forms.  4, record 2, English, - pressure%2Dtype%20anemometer

[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.
