Flow-meters (used in volumetric coffee machines) control the flow of water to the group head, only allowing a predetermined amount to pass through.
Basically they have a star with a magnet inside, and each rotation of the star allows a calculate amount of rotation through, and as such it can deliver exactly 30ml (or any other determined amount).
