摘要：
The present invention relates to a flow meter comprising a fluidic oscillator stabilization chamber (1) comprising a stabilizer element of the flow (11), an oscillation chamber (2) comprising an element to reflux (21) is configured to create at least one gas eddy oscillating in the oscillation chamber (2), said element to reflux (21) being between two parallel walls (28, 29) defining the oscillation chamber (2), a connection duct (3) connected fluidically the stabilization chamber (1) to the oscillation chamber (2), and a plane of symmetry (p) between the connection duct (3), the stabilization chamber (1), the stabilizer element of the flow (11), the oscillation chamber (2) and the element to reflux (21) into two equal parts and symmetrical with respect to the plane of symmetry (p). One of the two parallel walls (28, 29) comprises two orifices of measurement (24, 25) arranged symmetrically with respect to the plane of symmetry (p), and the connecting duct (3) has a rectangular cross section. Monitoring device or of compliance of a treatment of oxygen, comprising such a flow meter to fluidic oscillator and installation of oxygen, comprising a respiratory gas source, an interface of the distribution of gas and such a device for monitoring or compliance.Linvention concerne un débitmètre à oscillation fluidique comprenant une chambre de stabilisation (1) comprenant un élément stabilisateur de flux (11), une chambre doscillation (2) comprenant un élément à reflux (21) configuré pour créer au moins un tourbillon gazeux oscillant dans la chambre doscillation (2), ledit élément à reflux (21) étant compris entre deux parois parallèles (28, 29) délimitant la chambre doscillation (2), un conduit de liaison (3) reliant fluidiquement la chambre de stabilisation (1) à la chambre doscillation (2), et un plan de symétrie (P) séparant le conduit de liaison (3), la chambre de stabilisation (1), lélément stabilisateur de flux (11), la chambre doscillation fluidique (2) et lélément à r
