Precision Filling for High-Viscosity Products: How Pressure Metering Fillers Improve Accuracy and Efficiency


Manufacturers that package thick sauces, spreads, pastes, and semi-liquid foods know that accurate filling can be challenging. Products with high viscosity don’t always flow evenly, and traditional gravity or piston fillers may struggle to maintain consistent portion control. That’s where a pressure metering filler from Laub/Hunt delivers a reliable and precise solution.


Laub/Hunt manufactures a full line of pressure metering fillers specifically designed for high-viscosity foods and semi-liquid products. These systems are engineered to handle thick, challenging materials while maintaining consistent fill volumes and smooth, efficient operation across a wide range of container sizes.


How a Pressure Metering Filler Works

In a pressure-metering system, the filling head is constructed from three plates sandwiched together. The upper two plates remain stationary, while the bottom plate rotates during operation. A middle Teflon plate provides an excellent bearing surface, allowing the rotating bottom plate to maintain a tight seal and consistent performance.


The upper plate contains one or more product inlet ports. The middle plate features channels that align with these inlet ports. The rotating bottom plate includes ports for each filling nozzle. As each nozzle port passes beneath the inlet port, product flows into the container. Once the port rotates out of position, the flow stops automatically. This precise timing ensures accurate fills with minimal waste or product variation.


Benefits of Pressure Metering Filling Systems

  • Consistent fill accuracy for thick and semi-liquid products
  • Smooth handling of high-viscosity foods like sauces, pastes, and spreads
  • Reduced product waste and improved yield
  • Reliable, continuous operation for high-volume production
  • Durable design engineered for food processing environments

These systems are ideal for applications such as peanut butter, cheese spreads, salad dressings, condiments, and other products that require controlled, consistent filling.

MASSFlow and MAGFlow Filling Technologie
March 18, 2026
The primary differences between MASSFlow and MAGFlow filling technologies lie in the type of meter used, their accuracy, and the specific products they are engineered to handle. 1. Meter Technology and Accuracy ● MASSFlow: This technology utilizes Coriolis flowmeters (typically Endress+Hauser DosiMass or Promass F models). It is highly accurate, consistently delivering a fill accuracy of +/- 0.25% (+/- 1/4 of 1%). ● MAGFlow: This technology uses magnetic flowmeters (specifically Endress+Hauser DosiMag models). While some applications for specific chemicals list an accuracy of +/- 0.25%, the general specification for MAGFlow systems is often cited at +/- 0.5% (+/- 1/2 of 1%) throughout the fill range. 2. Product Suitability ● MASSFlow Applications: These systems are extremely versatile and can handle a vast range of viscosities. They are used for motor oils, shampoos, conditioners, solvent-based stains, polyurethanes, and food products like canola or soybean oil. They are even capable of filling heavy materials like asphalt at temperatures up to 350°F. ● MAGFlow Applications: MAGFlow is specifically designed for conductive liquids . It is the preferred technology for aqueous, foamy, and bleach-based household cleaners or car wash products. 3. Operational Requirements and Versatility ● MAGFlow Constraints: For maximum accuracy, MAGFlow requires liquids to be supplied at a constant density, pressure, and temperature . The product must also be free of entrained air or emulsified gases, which can vary the apparent density and affect the meter reading. ● MASSFlow Versatility: MASSFlow systems allow for individual head calibration via the HMI (Human Machine Interface) and can store pre-programmed "recipes" for over 100 different product/bottle combinations. They are best suited for filling volumes ranging from 0.5 to 128 oz. Both systems are often housed on similar frames (T304 or T316 Stainless Steel) and feature "No Bottle, No Fill" nozzle technology to prevent waste. Contact us for more information.
