LAG-14 ER
3.1
Application area
Tanks
Only the following tanks are approved: double-walled containers
(tanks) which are operated under atmospheric conditions and which
comply with the standards DIN 6616 type A, DIN 6623-2, DIN 6624-
2, EN 12285-2 (type D) and EN 12285-1 (type D) or which have an
approval that the interstitial space is suitable for connection of a liq-
uid-based leak detection system.
The interstitial space volume of the system must not exceed 1 m³.
Stored liquids
Only the following liquids are approved:
•
Water-polluting liquids.
•
Flammable liquids with a flash point of > or
≤
55 °C.
Approved storage media
If the containers (tanks) are operated under atmospheric conditions
and depending on the design of the containers (tanks), water-pollut-
ing liquids with the following densities may be stored in the contain-
ers (tanks):
•
Tanks as per DIN 6616 type A, DIN 6623-2 and DIN 6624-2
≤
2.5 m Ø permissible density
≤
1.90 g/cm³
≤
2.9 m Ø permissible density
≤
1.85 g/cm³
CAUTION
Danger of reaction of leak detection fluid and stored liquid if un-
suitable leak detection fluid is used.
The leak detection fluid and the stored liquid may not react.
Proven compatibility is required.
Observe the information on the intended use in chapter 2.1,
page 5.
3.2
Function
The LAG-14 ER leak detector monitors the interstitial space of dou-
ble-walled tanks filled with leak detection fluid. In the case of a leak
in the inner or outer wall of the container (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 leak detection fluid to fall. The
electrode rods of the probe are no longer submerged in the leak de-
tection fluid. The control unit detects the change in resistance, gener-
ates visual and audible alarms and actuates the output relay.
