4.4 Function
The product monitors the interstitial space of double-walled tanks filled with
leak detection fluid.
The probe is plugged into the top of the container for the leak detection fluid.
A small current flows between the electrodes through the conductive leak
detection fluid. In the case of a leak in the inner or outer wall of the tank,
above or below the levels of the stored liquid or the ground water, the leak
detection fluid escapes. This causes the level of the liquid in the leak detec-
tion fluid container to drop and the electrode rods of the probe are no longer
submerged.
The control unit detects the interruption of the flow of the current (switching
point for the alarm) and the product triggers an alarm.
