One of the two parallel walls (28, 29) comprises two measurement orifices (24, 25) arranged symmetrically with respect to the plane of symmetry (P), and the connection conduit (3) has a rectangular cross section. Device for monitoring oxygen 0 therapy, comprising such a fluidic oscillation flowmeter, and oxygen therapy equipment comprising a source of respiratory gas, a gas distribution interface and such a monitoring device.1/7 24 d1 Z1 23 15 4 12 d22 27P 1 132 2 6 11 15 2 414 5 2 5 Z2 21 2 L 3 24 28 21 25 29 FIG.2
