Advanced Weight-Based Dosing Systems for Drums, Pails & Jerrycans.
Our automated gravimetric filling lines deliver unmatched accuracy for challenging liquids – from aggressive chemicals to food concentrates. Engineered with tensionetric load cells (±0.1% precision), these systems outperform piston pumps and flow meters in precision while handling viscosities up to 50,000 cP.
Core Applications:
Chemicals: Detergents, automotive fluids, industrial solvents (including ATEX-certified handling of flammables)
Food: Concentrates, colorants, liquid raw materials
Specialty: Foaming, corrosive, explosive, or viscous products
Container Loading: Operator loads empty containers onto infeed conveyor/orienter
Indexing: Containers transfer to filling zone via powered roller conveyor
Container Positioning: Pneumatic stoppers secure batch on weigh platforms
Precision Filling:
Dosing nozzles descend to container base
Gravimetric filling initiates with upward nozzle retraction
Continuous weight monitoring until target dose (±0.05% accuracy)
Capping: Oriented caps applied via vibratory bowl > linear capper (chuck-type/roller-head)
Labeling: Up to 5 labels applied with wrap-around/pressure-sensitive systems
Marking: Laser or CIJ coding for batch/expiry data
Group Packaging: Automatic case packing, shrink wrapping, or palletizing
| System Type | Throughput | Key Components | Operator Role |
|---|---|---|---|
| Semi-Auto | 100-400 cont./hr | Manual turntable, suspended capper | Container handling, cap placement |
| Fully Auto | 400-800 cont./hr | Linear filler, auto cap orienter, CIJ coder | Infrequent monitoring |
| High-Speed | 800-1,200+ cont./hr | Multi-nozzle filler, robotic capper, palletizer | Minimal intervention |
Weight-dispensing filling lines combine precision weighing technology with automated liquid handling for high-accuracy filling. Key components include:
Load cells with ±0.1% measurement accuracy
Peristaltic/piston pumps handling viscosities from 1-50,000 cP
PLC-controlled dosing with recipe memory for rapid changeovers
Stainless steel construction (SS304/SS316L) meeting GMP, FDA, and ATEX standards 114
Application-Specific Engineering.

AI-Driven Optimization: Machine learning for predictive maintenance and yield optimization
Robotic Palletizing: Integrated cobots for end-of-line packaging
IIoT Connectivity: Real-time OEE monitoring via cloud platforms
Sustainable Engineering: Energy-recovery systems reducing power consumption by 30%
| Metric | Gravimetric Systems | Piston/Flow Meters |
|---|---|---|
| Accuracy | ±0.05% (doses >20L) | ±1-2% (viscosity-dependent) |
| Changeover | <15 min (recipe recall) | 30-60 min (recalibration) |
| Product Flexibility | Handles foaming/hazardous materials | Limited by viscosity/seal wear |
| Maintenance | CIP-compatible sensors | Complex seal/piston replacement |
✅ Future-Proof Automation: Integrates with robotic palletizers and MES software
✅ Explosion-Safe Design: ATEX/IECEx compliance for solvents/LVH fluids
✅ Hygienic Construction: SS316L product contact, IP65 electronics
✅ Zero Product Waste: Eliminates overfill costs (saves 10-25% vs. volumetric)
Gravimetric technology outperforms flow meters in precision, speed, and flexibility – especially when filling corrosive or explosive liquids into large containers.
