How does the atmospheric filling machine control the water level in the bottle?

That depends on how much you invest. If it is larger, the liquid level controller can be installed on the filling valve, which has better effect, but the cost is also high. The price is about 2000 yuan, and the investment is small. You can convert it into isobaric, and control the liquid level by air pressure. The advantage is that it is cheap, but the disadvantage is that the liquid level consistency is not enough.
