Essential Parts of a Volumetric Bottle Filler

Volumetric bottle fillers are essentially multi-purpose systems designed to serve several roles. To satisfactorily fulfill these roles, they are endowed with multiple components, each customized to serve a different role.

Container Handling System

This is essentially the feed system, which is made up of high-volume tanks specialized to hold your bulk product before bottling. This is also referred to as the hopper and it may come in varying capacities or designs. The handling system is also fitted with dispensing components like rotary lobe pumps.

Dosing System

The dosing system is linked to filling nozzles and is tasked with dictating the volume of product each nozzle injects into your bottles. Contemporary volumetric fillers are endowed with automatic dosing systems and this guarantees you a steady product volume. Common dosing systems installed in volumetric fillers include flow meters, timers, and level sensors.

Filling Nozzles

Filling nozzles are spouts attached to small tubes and tasked with transferring your product from the bulk reservoir into your respective bottles. Their opening and closing are meticulously controlled by your filler’s control system and this results in precise fill levels. They come in varying designs including;

  • Spring-loaded nozzles.
  • Diving nozzles.
  • Anti-drip nozzles.

Conveyor System

Filled bottles must be transported to the capping system and the labeling machine. This is typically accomplished with the help of conveyors. These conveyors are also crucial in moving empty bottles to their respective filling areas.

You can adjust the layout and speed of your filler’s conveyor depending on your production demand. Common conveyor systems include belt conveyors and slat conveyors, which are available in unique designs like rotary, straight, and indexing.

Capping System

Once your bottles have been filled, they must be sealed instantly to avert contamination and spillage. This is why most volumetric bottle fillers come with an integrated capping system. The filled bottles are transported to the capping system using conveyors before being tightly sealed.


The controller is the chief operating component tasked with controlling and coordinating the operation of the other components. Most controllers on modern volumetric bottle fillers are computerized and can support remote monitoring.

Volumetric Bottle Filler Features

  • Automatic Bottle Handling: These fillers utilize automatic control systems, conveyors, and dispensing nozzles thereby minimizing the need for human input.
  • Multiple Filling Nozzles: Volumetric fillers come equipped with several filling nozzles thus allowing you to fill multiple bottles simultaneously.
  • Overflow System: They also have an overflow system, which ensures that the excess product is reinjected into the reservoir thereby minimizing wastage.
  • High Precision: Volumetric bottle fillers rely on proven dispensing technologies like pistons and flow meters and this translates into precise filling.
  • Adjustable Filling Volumes: using the control board, you can adjust the fill level and other specifications. You can also modify the filling nozzles to accommodate differently sized or designed bottles.

How a Volumetric Bottle Filler Works

  • Bottle Placement: First, the containers to be bottled are strategically and carefully arranged on a conveyor system. This conveyor system then transports the bottles to their respective filling stations, placing one bottle per nozzle.
  • Bottle Centering: Once the bottles arrive at their respective filling stations, they are carefully positioned beneath the respective nozzles. This averts spillage which can lead to losses and pose a contamination risk.
  • Filling: With the bottles centrally positioned, the filling process is initiated. In automatic volumetric fillers, the filling nozzles are instructed to open by a pre-programmed control board. Once the pre-determined fill volume is attained, these valves or nozzles close down automatically.
  • Volume Adjustment: To ensure that your volumetric demands are adequately met and uniform across all your bottles, the fil level is adjusted. This is accomplished with the help of level sensors and overflow monitors.
  • Container Exit: Once the perfect volumetric level is attained, the filled bottles are seamlessly ejected from the filling station. In most volumetric fillers, they are moved to the capping machine by a conveyor belt.
  • Capping: The majority of high-level volumetric bottle fillers come with integrated capping units. Once the bottles are delivered at the capping station, they are tightly sealed to mitigate spilling and contamination.

Why You Should Use a Volumetric Bottle-Filling Machine

By focusing on the volumetric metric of bottle filling, volumetric bottle fillers manage to achieve unrivaled precision degrees. Their use can be beneficial to you in several ways:

  • Precise Measurements: A volumetric bottle filler will ensure that your bottle’s volume is not higher or lower. The volume of your product is guaranteed to be precise.
  • Volume Consistency: Forget about uneven fill levels thanks to volumetric bottle fillers. These systems fill your bottles with the exact same volume of product at all times.
  • Increased Production: With a volumetric filler, you can bottle multiple containers instantaneously thanks to their multiple nozzle configuration.
  • No Room for Human Error: Human input, although reliable, comes with inconsistencies which can be costly. However, using a volumetric filler eliminates these variations resulting in consistent and accurate fill levels.
  • Reduced Downtime: Volumetric bottle fillers can operate continually without deteriorating production levels. The same cannot be said about manual bottle filling.
  • Versatility: You can use volumetric fillers to dispense distinct types of products into bottles. You can also use them to fill distinctly sized and shaped containers.

Limitations of Volumetric Bottle Fillers

Volumetric bottle dispensing machines are undoubtedly highly beneficial systems, particularly in manufacturing industries. However, their utilization comes with a few limitations, which are luckily, not a deal breaker.

  • Viscosity Limitations: When filling liquid products with extremely high viscosities, the accuracy of volumetric bottle fillers drops. This can lead to uneven fill volumes in your bottled products.
  • Inability to Handle Foaming Liquid: If used to dispense foaming fluids like beer into bottles, the fill volumes attained may differ. This results in inconsistent fill levels, which can harm your brand’s reputation.
