A dispensing device for dispensing a dose of an additive to a liquid that is flowing in a pipe, the dispensing device comprising:
- a headpiece with an inlet and an outlet for connecting the dispensing device to the pipe,
- a housing connected to the headpiece and having an interior volume in which the additive can be contained, and
- an audio generator that does not generate sound when the amount of the additive contained in the interior volume of the housing exceeds a prescribed amount, and that uses liquid flow through the dispensing device to generate sound to provide an indication that the amount of additive has dropped below the prescribed amount.
