Flowability
The product must flow into and out of the cup without bridging, sticking or inconsistent settling.
Volumetric cup fillers UK
Volumetric cup fillers for granules, seeds, beans, sugar and dry products.
Volumetric cup fillers dose a measured cup volume of free-flowing product. They are considered for granular products where cup volume repeatability is practical and product density is reasonably consistent.

Specification route
Use cup dosing when the dry product flows consistently.
Cup fillers are different from liquid piston fillers. The key decision is whether the granule or dry product flows consistently enough for volumetric cup dosing or whether auger or weigh dosing should be compared.
- Useful for free-flowing granules such as beans, seeds, coffee, sugar, grains, pellets and similar products after testing.
- Cup size, product density and vibration affect fill repeatability.
- Powders, sticky products or variable-density products may need auger or weigh-based comparison.
- Can be integrated with conveyors, jars, bags, pots or other packaging formats where suitable.
Selection checks
What affects the machine shortlist?
These checks improve the match between the product, filling method and production layout before quotation.
Bulk density
Variations in density affect weight even when the cup volume is consistent.
Target tolerance
A cup filler may be suitable where the required tolerance matches how the product behaves in the cup.
Pack format
Bag, jar, tub or pouch handling can change the dosing height, support and discharge arrangement.
Machine formats
Routes to compare before buying.
The strongest enquiry usually compares two or three realistic machine routes against the real production conditions.
Fixed or adjustable cup dosing
Selected according to fill volume range, changeover and product consistency.
Auger dosing comparison
Useful for powders or products that do not flow cleanly through a cup system.
Weighing comparison
Considered when final pack weight tolerance is tighter or product density varies.

FAQs
Common questions about volumetric cup fillers uk.
It is a machine that doses a measured cup volume of dry or granular product into a container or pack.
Sometimes, but powders often need auger or weighing routes. Flow testing is important before specifying cup dosing.
No. It fills by volume. The final weight depends on the product bulk density and how consistently the product fills the cup.
Yes. Cup dosing can be integrated into automatic packaging lines depending on product, pack type and output target.

Cup dosing engineering
A volumetric cup repeats space; the product's bulk density determines the resulting mass.
Cup filling is a practical high-speed route for free-flowing granules when the product enters, levels and discharges consistently. It should not be described as direct weight control, even when a reference range is displayed in grams.
Fill the cup consistently
Hopper level, vibration, feed rate, product size distribution and levelling must produce the same packing condition in the cup. Bridging, segregation or aeration can change the quantity before the cup rotates or opens.
Discharge the cup completely
The outlet and funnel must suit the largest particle and container opening. Static, moisture, surface texture and product damage can cause retention. A partial discharge produces low fills even if the cup itself was full.
Control the density envelope
Measure loose and settled bulk density for representative batches. Convert the cup volume into the expected mass range, then compare that range with the buyer's tolerance before selecting volumetric rather than weigh dosing.
Verified cup-filler reference
LU-KL02S published configuration.
| Parameter | Published first-party value | How to interpret it |
|---|---|---|
| Measurement method | Measuring cup | The machine meters a defined volume; the product's bulk density determines mass. |
| Filling reference | 1–500 g, customisable | This is product-dependent and must be validated with the actual granule and cup setting. |
| Published speed | 10–30 bottles/min | Depends on product flow, dose, container handling and integration. |
| Hopper | 30 L; approximately Ø320 × 410 mm | Hopper level and feed behaviour should remain stable during the production trial. |
| Outlet reference | 20 mm, other sizes customisable | The outlet must pass the maximum particle without retention, blockage or damage. |

Cup trial and changeover
Test density variation as well as short-term repeatability.
Collect individual results from representative product batches, not only one freshly mixed sample. Record product condition, cup setting, hopper level, vibration or feed setting, cycle rate and any retained product. Repeat the check after the cup or funnel is removed for cleaning and refitted.
Stay with cup dosing when
- The product is genuinely free-flowing and fills the cup consistently.
- Bulk density is stable enough for the accepted mass or count tolerance.
- The particles discharge without damage or retention.
- Fast, mechanically simple volume dosing suits the pack.
Compare another route when
- Density changes materially between batches or during the run.
- The sale quantity is controlled directly by mass.
- Fine powder bridges, compacts, aerates or generates excessive dust.
- Mixed particle sizes segregate or cannot discharge consistently.

Buyer questions
Volumetric cup and bulk-density questions
These answers explain the checks that normally need to be completed before a machine configuration can be confirmed.
The cup controls volume. If the product becomes more or less dense because of settling, size distribution, moisture or aeration, the same cup volume can contain a different mass.
The product should flow into, level across and leave the cup consistently without bridging, excessive dust, damage or segregation. The real bulk-density range must also fit the accepted quantity tolerance.
Set the cup, run representative product, measure individual discharged quantities and record the setting. Repeat at the product-density boundaries and after the cup is removed and refitted.
An auger is commonly compared for fine, less free-flowing or cohesive powders where controlled screw movement gives more consistent feed than an open measuring cup.
Use weigh filling as the stronger comparison when target mass is primary, bulk density varies materially, or the required tolerance cannot be held by a fixed volume.
The project may require different cups or cup settings, outlet or funnel sizes, container guides and timing settings. Cleaning access and prevention of cross-contamination should be included.

Bulk-density worksheet
Translate cup volume into expected mass before setting the acceptance test.
A cup filler repeats a defined space. When packs are checked by mass, the expected result is governed by the bulk density of the product occupying that space. The basic relationship is expected mass = cup volume × bulk density, provided the units are consistent.
| Record | How to collect it | How it informs the cup setting |
|---|---|---|
| Loose bulk density | Fill a known reference volume using the normal gentle handling method and record mass without deliberate compaction. | Shows the lower-density condition that may occur after aeration or fresh product transfer. |
| Settled bulk density | Repeat the reference after the defined vibration, settling or handling expected before dosing. | Shows whether handling can increase mass from the same nominal cup volume. |
| Production density range | Sample different batches and the beginning, middle and end of the normal hopper operating range. | Defines the likely mass envelope before machine repeatability is considered. |
| Cup and adjustment reference | Record fixed or adjustable cup parts, depth or setting and any change parts. | Makes the accepted volume reproducible after cleaning or format change. |
| Feed and hopper condition | Record hopper level, agitation or vibration, feed-gate setting and line speed. | These conditions affect how completely and consistently the cup is filled and struck off. |
| Retention and discharge | Inspect product left in the cup, transfer chute and outlet after each cycle. | Incomplete release means the delivered quantity can differ even when cup filling is stable. |
Calibration sequence
Set the cup from the density envelope, then verify the production sequence.
1. Define the target basis
State whether acceptance is by volume, mass or count. Where a declared pack quantity is by mass, use the observed bulk-density range to estimate the cup volume that deserves a trial; do not treat the formula as final calibration.
2. Stabilise cup filling
Run the normal hopper level, feed and line speed. Observe overfill, voids, strike-off, product breakage and carry-over before adjusting the cup solely from a small set of weights.
3. Sample the full run
Retain sequential results from start-up, steady production, replenishment and the low normal hopper condition. Record each setting and density observation so mass changes can be separated from mechanical variation.
When cup dosing remains the right route
Cup dosing is strongest where the granule flows freely, density stays within a controlled envelope, the product fills and releases from the cup consistently, and the agreed tolerance can be met across batches. Count-sensitive products also need checks for breakage, doubles, voids and piece-size variation.
When to compare another principle
Compare auger and volumetric dosing where powder flow or dust makes cup filling unstable. Compare weigh and volumetric filling when mass must remain controlled despite material density changes. The wider Lancing weighing-machine range is kept on Weigh Fillers UK.
