Choosing the Right Filling Technology for Your Product

Filling technology selection is driven by four variables: product viscosity, unit value, required accuracy and regulatory context.

Gravity and time-pressure filling suit low-viscosity, low-value products where ±1.5% accuracy is acceptable and capital cost dominates the decision.

Volumetric piston filling handles viscous and particulate products reliably, and remains the pragmatic choice for sauces, creams and gels.

Flow-meter filling with mass-flow verification delivers the tightest accuracy on high-value liquids, and its data output supports validated environments naturally.

Net-weight filling is the answer whenever product cost per litre is high enough that giveaway of even 0.5% outweighs the capital premium — increasingly common in pharma and specialty chemicals.
