ABSTRACT:
A wind velocity measuring apparatus tips over when a predetermined wind velocity is reached or exceeded. The apparatus includes a base adapted to rest on a horizontal supporting surface such as a roof. An upright member extends upwardly from said base and carries at its upper end a wind impeding device in the form of a cylindrical vane or a plurality of radially extending, arcuately spaced vanes. A "telltale" device is sealed within the base to indicate when the apparatus has been tipped over by wind equalling or exceeding the predetermined velocity.
