Choosing the right oil filling machine is not just about production speed—it also depends on your product characteristics, filling accuracy, and future production plans. Two of the most widely used technologies are piston filler and flow meter filling, each offering unique advantages for different applications.
Understanding how these systems work can help manufacturers make a more informed investment.
How Do They Work?
A piston filler measures liquid by drawing a fixed volume into a piston cylinder before dispensing it into the container. This technology is well suited for products with higher viscosity or applications requiring consistent volumetric filling.
A flow meter filling system measures the actual volume or mass of liquid passing through a flow meter in real time. It is widely used for edible oils, lubricants, and other free-flowing liquids where high filling accuracy and production efficiency are required.

Which Solution Is Right for Your Project?
There is no single filling technology that fits every production line. Product viscosity, bottle type, production capacity, and automation requirements should all be considered before selecting equipment.
Shanghai Leadworld provides both piston filler and flow meter filling solutions as part of customized turnkey filling lines. Rather than offering standard machine configurations, each system is designed according to the customer's product characteristics, factory layout, and long-term production goals.
Whether you are packaging edible oil, lubricating oil, or other liquid products, selecting the right technology can improve filling consistency, reduce product waste, and support future production expansion.
With exports to more than 100 countries and regions and certifications including CE, ISO9001, and SGS, Shanghai Leadworld continues to deliver customized oil filling solutions that combine reliability, flexibility, and long-term value.
