Pump-and-scale liquid filling
A pump delivers product while the scale controls cut-off at the target weight.

Weigh filling machines for accurate liquid and dry-product dosing
Weigh filling controls the dose using live mass feedback. It can reduce the effect of density variation and is useful for products sold or controlled by weight, but the scale must settle quickly and the feed must stop cleanly. Liquid, powder and granule weigh fillers use different feed mechanisms even though the measurement principle is similar.
Typical products and packs
Where this filling route is used
- Oils and larger liquid fills
- Powders with variable bulk density
- Granules, pieces and free-flowing foods
- Pails, jerrycans, drums and retail containers
Compare the principles
Relevant machine routes
Several dosing methods may fill the same nominal product. The practical choice is driven by accuracy, cut-off, cleaning, format range and sustained output.
Net-weight powder filling
A feeder meters powder into a weigh bucket or directly into the container.
Explore this routeLinear weigh filling
One or more weigh heads dose granules at moderate speeds.
Explore this routeMultihead combination weighing
Multiple weigh hoppers combine to reach target weight at higher output.

Weigh filling machines FAQs
What products suit weigh filling machines?
Typical applications include oils and larger liquid fills, powders with variable bulk density, granules, pieces and free-flowing foods. The final decision depends on the real product, dose, container and target output.
How do I choose weigh filling machines?
Start with the product behaviour, fill range, pack format and sustainable output. Then compare the dosing principle, contact materials, changeover and cleaning against live weight feedback and clean feed cut-off.
Can the filler be supplied as part of a complete line?
Yes. Filling can be planned with container infeed, conveyors, capping or closing, labelling, coding, sealing, inspection, accumulation and end-of-line handling.
What information is needed for a quotation?
Send product details and safety data where relevant, fill volumes, container and closure samples or drawings, target output, utilities, cleaning needs, footprint and any existing equipment to be integrated.
