Sample applications

How do SGB leak detectors work? We’ll show you in our animated examples.

Pressure leak detectors

Several underground double-walled tanks (monitored with air)


Several underground double-walled pipes (monitored with air)


Underground, double-walled pipe (monitored with nitrogen)

Vacuum leak detectors

Horizontal cylindrical tank


Vertical cylindrical tank


Tank with leak protection lining and suction line to the low point of the interstitial space


Double-walled floor of a flat-bottomed tank


Double-walled pipe for conveying liquids with a flashpoint of 55 °C (for Germany; otherwise 60 °C), e.g. petrol


Several double-walled pipes via a manifold
