Abstract: The invention relates to a fluid meter comprising an outside wall of determined thickness to which a flange connected to a pipe is fixed via fixing members which penetrate into holes organized respectively in the thickness of said flange and in said outside wall in order to install said meter on said pipe, said meter having an opening for fluid feed which is organized in the outside wall and behind which there is provided a “feed” chamber into which the fluid coming from the feed opening flows, wherein the fluid meter also has studs disposed inside the feed chamber so as to modify the fluid flow, and in which internal perforations are provided in alignment with the holes for receiving portions of said fixing members.

Abstract: The invention provides a fluidic oscillator that is symmetrical about a longitudinal plane of symmetry (P), comprising an enclosure defining an oscillation chamber and having an inlet opening and an outlet opening through which the fluid flows and which are in alignment in said plane (P) in a “longitudinal” first direction (A), said inlet opening being made in the form of a slot that is narrow in a second direction (B) extending transversely to said plane (P) and elongate in a third direction (C) parallel to said plane (P) and perpendicular to said longitudinal first direction (A), wherein said slot is provided in an insert which is removable from said enclosure.

Abstract: The invention concerns a fluid meter including a body comprising a fluid intake opening and a fluid evacuation opening aligned along a first direction A, a measuring unit formed of a fluid oscillator including at least one obstacle disposed into an oscillation chamber and which is provided with one fluid inlet and one fluid outlet, characterized in that the inlet and outlet of the fluidic oscillator are aligned along a second direction C approximately perpendicular to the first direction.
