Linear filling machines based on flow meters are used in all applications where high filling accuracy and repeatability of the dose are required.
This includes the food, pharmaceutical, and cosmetics industries, as well as the petrochemical industry. These machines are optimally cleaned using CIP/SIP technology.
The filling system is characterised by high reliability and minimal maintenance requirements.
Mass flow meters eliminate the influence of product temperature, thus ensuring the same dose is achieved at different filling temperatures.
The performance of a mono-rail machine moves between 1,000 and 5,000 bottles per hour, on two-rail system up to 8,000 bottles per hour.

Process Description
- The containers are conveyed into the machine on a conveyor belt with a plastic or stainless steel belt. Before entering the filling area, the containers are stopped by a pneumatic infeed gate. As soon as the previous group of filled bottles leaves the filling station, the gate opens, allowing the next group of bottles to enter. After the next group has entered, the infeed gate closes again. If one or more bottles are missing, the system waits and the filling process will not start.
- After all the bottles have been run in, the filling process is started. As soon as the bottle necks are automatically centred, the nozzles dip into the bottles and open. The filling quantity is measured by flow meters. Pumps or a pressure vessel can be used for dispensing the product. The filling volume can be set via the touchscreen, which allows for quick and easy changes to the volume and filling parameters.
- After the filling process is completed, the nozzles close, and a drip tray moves under the nozzles to prevent contamination of the bottles. Subsequently, the discharge flap opens, and the units are released from the filling plant.
