Choosing the Right Filling System: Gravity, Pressure, and Balanced Options Explained
April 7, 2025
When it comes to selecting the ideal filling solution for your operation, understanding the options available for filling to a level is crucial. At Laub/Hunt, we offer a full range of precision filling systems tailored to your specific product, container, and production goals.
Explore the Range of Level Fill Technologies
There are several proven methods for achieving a consistent fill level in packaging:
- Gravity Fill: This is the simplest and most reliable method, ideal for water-thin products. Gravity systems rely on consistent head pressure, ensuring uniform fill levels with minimal maintenance. It’s a cost-effective and efficient choice for many industries.
- Gravity/Vacuum Fill: A hybrid option that enhances gravity filling by introducing vacuum assistance for more controlled performance in certain applications.
- Pressure Fill: Designed to handle more viscous liquids, this method applies controlled pressure to achieve fast and accurate fills. It’s perfect for increasing throughput while maintaining quality.
- Balanced Pressure Fill: By precisely balancing the pressure in both the tank and container, this system is ideal for heavier viscosity products. It improves fill accuracy and boosts overall production efficiency.
- Balanced Vacuum Fill: A preferred choice for
glass containers, this method reduces foaming and product loss by gently drawing liquid into the container via vacuum. It’s a smart solution for delicate packaging needs.

At Laub/Hunt, we specialize in Pressure Metering Fillers designed for high-viscosity foods and semi-liquid products. These systems are built to handle challenging applications while delivering precise, consistent fills every time. The heart of the Pressure Metering system lies in its innovative filling head. This head is made of three plates carefully engineered to work together: The top two plates remain stationary to stabilize the flow. The bottom plate rotates , controlling the product’s movement and ensuring accurate portioning. This unique design allows for efficient filling of products that are too thick or uneven in texture for standard filling systems. From sauces and creams to chunky spreads and semi-liquid foods, our Pressure Metering Fillers are built to keep production lines running smoothly without sacrificing quality. Manufacturers trust Laub/Hunt for equipment that is durable, easy to maintain, and adaptable to a variety of product types. By combining precision engineering with robust construction, our fillers offer long-term reliability in even the most demanding environments. Looking to upgrade your filling line? Contact Laub/Hunt today to learn how our Pressure Metering Fillers can improve your efficiency and deliver unmatched accuracy in your production process.
Information about Mag Flow (Magnetic Flow) Rotary Fillers Mag Flow (Magnetic Flow) Rotary Fillers are a type of filling machine commonly used in the beverage industry for filling liquid products into bottles or containers. These fillers utilize magnetic flow meter technology to achieve precise and accurate filling. Here's an overview of Mag Flow Rotary Fillers: Magnetic Flow Meter Technology: Principle: Mag Flow Fillers rely on the principles of electromagnetic flow measurement. When a conductive liquid flows through a magnetic field, it induces a voltage that is directly proportional to the flow rate. Accuracy: This technology provides high accuracy in measuring the flow rate of liquids, making it suitable for applications where precise filling volumes are crucial. Rotary Filling Mechanism: Design: Mag Flow Rotary Fillers are equipped with a rotary mechanism that allows bottles to move through the filling station in a circular or rotary fashion. Advantages: The rotary design enables high-speed filling operations, making these fillers suitable for high-throughput production lines. Bottle Handling System: Conveyor System: Bottles are typically transported on a conveyor system that moves them through different stations, including filling and capping. Indexing: The rotary mechanism indexes the bottles through each station, ensuring that they are precisely positioned for filling. Filling Process: Precision Filling: Mag Flow technology ensures accurate and repeatable filling volumes. The flow meter measures the liquid flow rate, and the filling nozzles dispense the exact amount of product into each bottle. Clean Filling: These fillers are suitable for filling a variety of liquid products, including beverages, and are often used in applications where cleanliness and hygiene are essential. Capping Station: Integration: Mag Flow Rotary Fillers are often part of a larger packaging line that includes a capping station. After filling, bottles move to the capping station where caps are applied and secured. Control System: Automation: These fillers are typically equipped with an automated control system that oversees the filling process. This system ensures that the correct fill volume is maintained, and it may interface with a central control system for the entire packaging line. Cleaning and Maintenance: CIP (Clean-in-Place): Mag Flow Rotary Fillers are designed to facilitate cleaning between product changeovers. Some models may have integrated Clean-in-Place systems to streamline the cleaning process. Versatility: Product Range: Mag Flow Rotary Fillers are versatile and can handle a wide range of liquid products, including carbonated and non-carbonated beverages, juices, water, and more. These fillers are a popular choice in industries where precise and high-speed filling is required, and the use of magnetic flow meter technology enhances their accuracy and reliability in achieving consistent fill volumes.
