Abstract

The invention relates to a fluidic oscillation flowmeter comprising a stabilization chamber (1) comprising a flow-stabilizing element (11), an oscillation chamber (2) comprising a reflux element (21) configured to create at least one oscillating gaseous vortex in the oscillation chamber (2), said reflux element (21) being arranged between two parallel walls (28, 29) delimiting the oscillation chamber (2), a connection conduit (3) fluidically connecting the stabilization chamber (1) to the oscillation chamber (2), and a plane of symmetry (P) separating the connection conduit (3), the stabilization chamber (1), the flow-stabilizing element (11), the fluidic oscillation chamber (2) and the reflux element (21) into two equal and symmetrical parts with respect to said plane of symmetry (P). 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 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.
