DescriptionWhat is the current situation?
As we know, the process of detecting gas leaks is as follows: The gas enters the soil and spreads there. Diffusion processes and the different densities of the soil air and gas cause the gas to finally rise to the surface of the ground. Sealed or wet surfaces are more difficult for the gas to pass through. Leaks can only be localized if the gas rises to the surface of the ground voluntarily and in sufficient quantities.
And this is where vacuum technology helps.
Before the gas reaches the surface, it has accumulated in the ground and lies there as if absorbed by a sponge in higher concentrations than on the surface of the ground. To get meaningful indications on the gas detector even in particularly difficult situations, these cushions of gas are vacuumed.
