Very few bottles do not have any small differences in volume. Considering this fact is crucial for determining the type of filling system you will use for packaging. You may have noticed that in supermarkets or car stores, when you check the filling level, some bottles appear to have short filling compared to other bottles. They are likely filled with capacity filling machinery. The volume inside the bottle is correct, but due to the small difference in volume between the bottles, it looks very short.

Using a liquid level filling machine, all bottles will "appear" with the same volume because the filling level will be the same, but there will be slight differences in the actual filling amount, no short filling, but some slight overflow.

So this is a decision you must make in advance: volume level or liquid level? For the vast majority of products, the answer will be liquid filling, as it is cheaper and faster than volumetric filling, and when the bottle "looks" evenly filled, consumers of the product will not feel deceived. However, if the product must have an exact dosage for its use, or if the product is very expensive per ounce and a small giveaway may cost you a lot, especially in high production environments, capacity filling is the best solution.

One of the simplest and possibly oldest technologies designed by humans is the siphon principle. In this case, what we are discussing isShandong filling machineNew Yongke's siphon filling machine. Gravity flows into the fuel tank to maintain a uniform liquid level. Place some gooseneck valves upwards on the side of the tank and return them to below the tank level. Start the siphon and see, you have one
