The leak detection system without its own pressure generator (static) for the monitoring of double-walled tanks with a suction line for the leak detector to the low point of the interstitial space.
This leak detection system consists of 1 leak indicating unit and up to 6 explosion-proof sensors which are connected to the interstitial spaces pneumatically.
The interstitial space is evacuated once with an external pump to an underpressure of approx. 700 mbar. The leak detector monitors continuously the pressure in the system. The manometer (digital display) shows the current pressure.
VLXE-S 350 M
- With a suction line to the low point of the interstitial space
- Maximum diameter: 3 meters or double-walled bottom of a flat bottom tank
- Underpressure resistance of interstitial space: up to -800 mbar
Water-polluting liquids. The (possible) explosive vapor-air mixtures (also such ones that can arise through the stored/conveyed liquids in contact with air, humidity, condensation or the materials used) must be classifiable into gas group II A to II B as well as in the temperature code T1 to T4. Examples: petrol, diesel, AdBlue.
