Abstract

An improved gas meter device comprising at least one main unit wall chamber, in which a substantially flat opening is made, a secondary chamber delimited by a cover that rests on a part of the wall of said main chamber, means for gas supply of said secondary chamber, a plate covering said opening of said main chamber, a flexible membrane delimiting in said main chamber and with said plate, two separate measuring chambers, means for putting into communication alternatively said secondary chamber with the two said measuring chambers, respectively, through two holes made in the wall of said main chamber, means for alternately putting one of the two measuring chambers in communication with the outside when the other is placed in communication with said secondary chamber, characterized by the fact that said membrane it is held, in front of said opening, pressed between the edges of said opening and the edges of the plate, said plate comprising a flat surface portion of its outer wall, which cooperates with a flat complementary part of the surface of the plate. Wall of said main chamber, the plane of these surfaces forming an oblique angle with the plane of said opening, passing through the communication hole between said secondary chamber and the measurement chamber delimited by said membrane and said plate, these two called complementary surfaces.
