Abstract

Cet anémomètre du type portatif est muni d'un rotor repliable. Des coupelles légères 25 sont portées par des bras 24, lesquelles sont articulées dans un moyeu 10. Le moyeu peut coulisser sur une broche rotative 5 de sorte que son déplacement vers le haut entraîne les bras 24 vers le haut et place le rotor dans une position repliée à peu près dans le prolongement du boîtier 2, tandis que son déplacement vers le bas remet les bras 24 en position horizontale, active.
