(Designate Figure 1) An apparatus for filling containers with a liquid comprises a filler head having a closable nozzle and a displacement cylinder having a power-actuated reciprocating piston. The cylinder is operatively connected to the filler head and, through a non-return valve, to a storage container for the liquid. A programmable logic controller selects and controls the opening and closing times of the nozzle and the length and timing of the piston forward and return strokes such that a measured amount of liquid from the storage container is fed through the cylinder to the filler head and thence through the nozzle to a container.
