Method and device for testing pressurized gas bottles

摘要

The device uses a liquid tank (2) containing the pressurised gas bottle (3), with the liquid within the tank subjected to atmospheric pressure and the liquid level monitored, via an electronic measuring device, for detecting the expansion of the gas bottle when it is subjected to pressure. The measuring device may use a pressure sensor (4) incorporated in the wall of the liquid tank and a second reference pressure sensor (15), both sensors coupled to an electronic evaluation circuit (5).
