LOCUS ROBOTICS engineers high-accuracy weigh-fill solutions for high-value liquids and viscous products where ±0.1% dosing accuracy is critical.
| Feature | Gravimetric Fillers | Piston Fillers | Flow Meter Systems |
|---|---|---|---|
| Accuracy | ±0.1% | ±0.3% | ±0.2% |
| Best For | High-value products | Viscous pastes | Thin liquids |
| Density Changes | Auto-compensation | Manual adjustment | Requires recalibration |
| Cycle Time | 15-30 sec/canister | 5-10 sec | 3-7 sec |
Key Advantage: Real-time weight feedback eliminates density/viscosity errors.
