摘要：
The invention relates to a fluidic oscillation flowmeter comprising a fluidic oscillation flowmeter comprising a stabilization chamber (1) comprising a flow stabilizing element (11), a first inlet (12) and a first outlet (13). ), the first inlet port (12) and the first outlet port (13) being arranged on the plane of symmetry (P), said flow stabilizing element (11) comprising a front face (1a) located opposite the first inlet port (12), an oscillation chamber (2) comprising a reflux element (21) comprising a cavity (21a) having a semi-circular section of diameter (D), configured to create at least one vortex gas oscillating in the oscillation chamber (2), said oscillation chamber (2) comprising a second inlet orifice (23) and a second outlet orifice (26) arranged on the plane of symmetry (P), a connecting duct (3) fluidly connecting the first discharge port tie (13) of the stabilization chamber (1) to the second inlet orifice (23) of the oscillation chamber (2), and a plane of symmetry (P) separating the connecting pipe (3), the chamber stabilizing element (1), the flow stabilizing element (11), the fluidic oscillation chamber (2) and the reflux element (21) in two equal parts and symmetrical with respect to said plane of symmetry (P). Device for monitoring or observing an oxygen therapy treatment comprising such a fluidic oscillation flowmeter and oxygen therapy installation comprising a respiratory gas source, a gas distribution interface and such a monitoring or compliance device.L'invention concerne un débitmètre à oscillation fluidique comprenant un débitmètre à oscillation fluidique comprenant une chambre de stabilisation (1) comprenant un élément stabilisateur de flux (11), un premier orifice d'entrée (12) et un premier orifice de sortie (13), le premier orifice d'entrée (12) et le premier orifice de sortie (13) étant agencés sur le plan de symétrie (P), ledit élément stabilisateur de flux (11) comprenant une face avant (la) située en regard du premier orifice
