... the pressure plate or normal plate anemometer. This is the oldest anemometer known, having been developed by Robert Hooke in 1667. ... The main application of this type of anemometer has been in gust studies because of its very short response time. Gusts of duration 0.01 s can be examined with this anemometer.  3, fiche 1, Anglais, - pressure%2Dplate%20anemometer

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.  5, fiche 1, Anglais, - pressure%2Dplate%20anemometer

pendulum anemometer.... The angular deflection of the plate is a function of the wind speed. This instrument is not used for station measurements because of the false reading which results when the frequency of the wind gusts and the natural frequency of the swinging plate coincide. This was the earliest form of anemometer.  4, fiche 2, Anglais, - pendulum%20anemometer

The first anemometer of any kind that we know about was a swinging-plate instrument, and was described and illustrated by Leon Battista Alberti at some time near 1450.  3, fiche 2, Anglais, - pendulum%20anemometer

[Fabrication d']un anémomètre à balancier avec un cadran en demi-lune. [...] Nous avons fixé à deux montants une barre de fer. [Fixée] à cette barre, une planche de bois fin se balance au gré du vent. Pour terminer, une autre planche, mais en forme de demi-lune cette fois, est graduée en kilomètres/heure.  3, fiche 2, Français, - an%C3%A9mom%C3%A8tre%20%C3%A0%20balancier
