Installation dimension a for the LDL tank in the scope covered by EN 13160-3
•
The installation dimension a is the distance between the top of the fuel tank and the
bottom of the LDL tank. The minimum installation dimension a
min
is to be determined
according to calculation equations [2] and [3] and must be complied with. The
installation dimension a
max
may not be exceeded and must be determined according
to calculation equation [4] and be complied with.

•
Distance between the check valve and the bottom of the LDL tank: ≥ 10 cm.

Table 6
The arrangement of the LDL tank for
above-ground and underground tanks
is shown schematically in
Fig.4
Note:
In Germany, installation of the
LAG 2000 A for underground tanks is
possible only within the scope of
replacing leak detectors.
