FIELD: sealing.
SUBSTANCE: group of inventions relates to leakage detection means in sealing membrane (5, 8) of a tank. Bell-shaped leakage detection device (55) contains main case (100) intended for placement in testing zone (62). Seal (60) is connected to main case (100), made with the possibility of limitation of detection chamber (61) between main case (100) and testing zone (62). At the same time, seal (60) contains peripheral sealing edge (64) having a closed contour for embracing testing zone (62). Bell-shaped leakage detection device (55) also contains a mechanical pressing means supported by main case (100), made with the possibility of exertion of pressure directed to membrane (5, 8) on seal (60).
EFFECT: reliability and ease of use.
