3.1 Manufacturer
See commissioned by
3.2 Type
DL .. / DLG ..
3.3 Application
Double walled tanks, single walled tanks with pressure-resistant jacketing and
double walled sumps and containments with sufficient pressure resistance
(see section No. 2 of the Technical Description dated 21 April 2004)
3.4 Design
The designation "overpressure leak detector type DL.. / DLG.." covers two
types which differ according to how pressure is generated and with regard to
the switching pressures. The units consist essentially of a pressure transducer
and a display/message unit, with electronic control and signal processing. Air
or inert gas can be used as leak detection medium, complying with the
maximum pressures on the bank bottom stated in Annex B of the Technical
Description.
