The beverage filling industries, in particular the beer industry, use kegs with different capacities to store their products

Since this is reusable packaging, it is necessary to ensure that the connection systems of the kegs are free from leakage, in order to maintain the quality of the product until it reaches the client.

Therefore, leakage inspection in the filling line is crucial, but it does carry significant technical difficulties. The traditional system – the weighing of the kegs and the inference of the liquid level – is far from being efficient.
