The invention relates to a storage and metering device intended for the injection of an additive (E) into a pipe (15) through which a variable-flow-rate liquid flows. The device is characterised in that it includes: a container (53) intended to house the additive and provided with an additive outlet (56) to be connected to the pipe, optionally by means of an injection system (22); and a differential pressure regulator (54) including a gas inlet (70) to be connected to a gas source (71), a gas outlet (74) connected to a pressurisation inlet (75) of the container (53) so that the container can be pressurised to a pressurisation pressure (PG) and a control inlet (78) to be connected to the pipe (15). |
