Installation location for the LDL tank
According to EN 13160-3, the LDL tank must be positioned so that:
•
the hydrostatic pressure of the leak detector liquid at the lowest point of the tank is at least
30mbar (= 3kPa) higher than the maximum pressure of the storage medium at the lowest
point of the tank (including working pressures) and also the maximum pressure of the
groundwater at the lowest point of the tank and
•
the pressure in the monitoring space does not exceed the nominal pressure of the
monitoring space
Remark 1: Here, the nominal pressure PN corresponds to the maximum permissible
pressure
p

Remark 2: The construction standards for tanks contain only information about the test
pressure of the monitoring space

but none about the maximum permissible
pressure in the monitoring space

•
the LDL tank must be positioned as follows
•
no surface or rainwater, dirt or windborne sand may get into the LDL tank, the sensor unit or
the cable connection fitting (accessory)
•
it must be protected against UV radiation
