Liquid Filling Systems – Accurate Weight-Based Filling for Drums, IBCs & Containers
Our liquid filling systems are precision-engineered solutions for the accurate, controlled filling of drums, IBCs, containers, and process vessels across chemical processing, food and beverage production, pharmaceutical manufacturing, and industrial operations. By using integrated weighing technology to control fill quantity by weight rather than volume, they deliver consistent, repeatable fill accuracy that reduces product giveaway, minimises waste, and supports batch traceability and compliance requirements.
Weight-based filling — also known as gravimetric filling — is the most accurate method for filling liquids, particularly where product density varies with temperature or batch, or where tight fill tolerances are required for regulatory or commercial reasons. Our systems combine precision load cells with programmable fill controllers, allowing operators to set target weights, tolerance bands, and automatic cut-off points for fast, accurate, and repeatable filling across a wide range of container sizes and liquid types. ATEX-certified configurations are available for filling flammable solvents and chemicals in hazardous area environments.

Frequently Asked Questions
What is gravimetric (weight-based) filling and why is it more accurate than volumetric filling?
Gravimetric filling measures the quantity dispensed by weight rather than volume. Because liquid density can vary with temperature, batch composition, and product type, volumetric filling can introduce errors when density changes. Weight-based filling is unaffected by density variation — the system fills to a precise target weight regardless of temperature or product variation, making it the most accurate method for demanding applications.
What fill accuracy can I expect from a gravimetric filling system?
Fill accuracy depends on the system configuration, container size, and product characteristics, but most gravimetric filling systems achieve ±0.1% to ±0.5% of target weight under stable conditions. For drum and IBC filling, accuracies of ±100 g to ±500 g on a 200 kg fill are typical. Contact our team for application-specific accuracy data.
Can filling systems handle flammable or hazardous liquids?
Yes. We offer ATEX-certified filling system configurations for use in Zone 1, Zone 2, Zone 21, and Zone 22 classified hazardous areas, suitable for filling flammable solvents, chemicals, and other hazardous liquids. All electrical components in the hazardous zone must carry the appropriate ATEX certification — contact our team to confirm the correct specification for your application.
Can filling systems be integrated with our ERP or production systems?
Yes. Most systems include data logging and connectivity options (RS-232, Ethernet, OPC-UA) for integration with ERP, MES, and batch management systems. This enables full batch traceability, automatic recipe selection, and production reporting. Contact us for integration advice specific to your systems.
Can filling systems be configured for different container sizes?
Yes. Most systems can be configured or programmed for multiple container sizes and target weights, with recipe storage allowing quick changeover between products and container formats. For high-volume production environments, automated container handling and conveyor integration can be incorporated. Contact our team to discuss your specific container range and throughput requirements.
