The invention relates to a storage and metering device intended for the injection of an additive into a pipe through which a variable-flow-rate liquid flows. The device is characterized in that it includes: a container intended to house the additive and provided with an additive outlet to be connected to the pipe, optionally by means of an injection system; and a differential pressure regulator including a gas inlet to be connected to a gas source, a gas outlet connected to a pressurization inlet of the container so that the container can be pressurized to a pressurization pressure and a control inlet to be connected to the pipe.
