LU-FM710 with separate weighing device
Approximately 10–2,000 g working envelope, 25 litre hopper and a separate scale for weight-assisted or volumetric operation.
Review LU-FM710
Fill accuracy options
Auger fillers with weigh feedback for improved powder filling control.
Review auger filling with weigh feedback when powder density changes, giveaway matters or finished-pack weight needs closer control.
Specification guidance
Use weighing where volumetric filling alone is not enough.
Standard auger filling is volumetric: each screw rotation moves an expected amount of product. If bulk density changes during production, finished pack weight can vary even when the auger movement is consistent.
Weigh feedback, checkweighing or gravimetric control can help when products are expensive, density varies or pack-weight tolerance is tight. The best option depends on speed, fill size and accuracy target.
Useful details for a quotation
- Powders with changing bulk density
- Higher-value products where giveaway matters
- Volumetric auger dosing with feedback correction
- Static weighing or downstream checkweighing options
- Specification around speed and tolerance targets
What to consider
Key choices before selecting the filler.
These points help narrow the auger, weighing, feed and line-integration options before a final specification is prepared.
Density variation
Weighing helps compensate when product density changes in the hopper.
Giveaway control
Better feedback can reduce overfilling where product cost is significant.
Speed balance
More weighing control can affect cycle time, so output should be reviewed.
Quick answers
Common questions about fill accuracy options.
When is weigh feedback useful?
It is useful when powder density varies, fill tolerance is tight or product giveaway is costly.
Does weigh feedback make filling slower?
It can affect speed depending on the control method, fill weight and tolerance target.
Is a checkweigher enough?
A downstream checkweigher confirms finished weight; weigh feedback may also help correct the filling process.

Weighing supports setup and verification, but it does not replace stable powder feed, correct tooling or an agreed quality-control method.

The selected scale or feedback system must be distinguished from an automatic inline checkweigher and from legal-for-trade weighing.
