What is a volumetric filler?

A volumetric filler is a machine which fills containers with a predetermined quantity of liquid, measured by the volume displaced rather than, for example, weight or height within a bottle.

Most volumetric filling machines consist of a pneumatically-powered linear actuator connected to a piston within a cylinder. The piston is forced forwards and backwards for each filling cycle.

During this motion, a valve at the opposite end of the cylinder governs the flow of liquid; allowing it to exit the cylinder from the outfeed side as the piston moves forwards and allowing the cylinder to draw liquid from the infeed side as the piston moves backwards.

The length of the piston’s stroke can be set to give the desired fill volume. The speed of the piston’s movement can also be controlled both fore and aft to ensure accurate filling volumes are achieved at acceptable speeds.

A filling nozzle is connected to the outfeed side of the metering cylinder’s valve, usually via a hose or pipe. This nozzle plays an important role in the filling process; it’s design, diameter and length should be specified to suit the liquid container and prevent dripping and any other undesired characteristics.

The infeed side of the metering cylinder’s valve is connected to either hopper or supply tank via a feed pipe, replenishing the cylinder as it moves backwards after each fill.

Universal Filling Machine Company manufacture several machines which use this filling principle and offer additional features such a secondary filling speed as an option. This allows for the latter part of the filling cycle to be completed at a reduced speed to avoid liquids splashing as a result of filling too fast. The speed and starting point of the secondary fill can both be set and have no effect on the overall filling volume.

Volumetric fillers can range from hand-operated, manual machines through to highly automated production lines and can fill volumes from 5ml to 5 litres in a single cycle. Multi-shot counters can also be used. These allow a number filling cycles to be completed in a single operation – a single press of the foot switch can be used to trigger 5×5 litre fills, giving a total of 25 litres in a single action.
