Abstract

The invention concerns a device for varying the dosage of an additive (A) in a main flow (P) of liquid, the proportioning being provided by a pump (1) driven by the main flow, the pump comprising a first intake (2) for the main flow, a second intake (3) for the additive and an outlet for the dosed mixture. A branch pipe (5) of the main flow is provided between a zone (6) located upstream of the first intake (2) and a zone (7) located downstream of the outlet (4), so as to enable a parallel flow not comprising the additive. Periodic control means (C) for the branch pipe (5) and the first intake (2) of the pump are also provided so that each control period comprises at least a phase (Ud1) for which the branch pipe (5) is open and the first intake (2) is closed, and another phase (Ud2) for which the branch pipe (5) is closed while the first intake (2) is open.
