The main characteristic of these machines is the dosage of the product inside the container, which can occur via a syringe device, or the filling system can be of electronic type to inductive flow metres for volumetric bulk filling for low conductivity products. This filling technology is able to guarantee the perfect amount of liquid inside the container used. Mainly this system is used with high density products such as sauces and oils, or very foamy such as liquid detergents or similar.
