Gas leakage monitoring of a gas or liquid container

摘要

The invention relates to a method and an apparatus for monitoring of gas leakage from a gas or liquefied gas container. For simple and reliable monitoring of gas leakage, parts of the container (1) where there is a risk of leakage are connected to an at least partially evacuated measuring chamber (2) and a change in the pressure in the measuring chamber (2) is employed as a measure of the gas-tightness of the container (1).
