Pressure (Overpressure) leak detectors for double walled tanks:

are preferably used for the monitoring of:

• liquids with a flashpoint < 55°C, as e.g. petrol, kerosene.
• chemically aggressive liquids, as e.g. lye and acids.

typical applications: petrol stations, industrial sites and chemical plants.

Vacuum (Underpressure) leak detectors for double walled tanks:

are preferably used for:

• the monitoring of liquids with flashpoint > 55°C, as e.g. heating oil, diesel.
• tanks, where the interstitial space is not suitable for overpressure for the storage of chemically aggressive and/ or explosive liquids.
• tanks and installations within areas with potentially explosive atmosphere (zoned areas).

typical applications:
tanks with linings, bulk storage tanks (flat bottom tanks) with double bottom, chemical plants, refineries, tank farms and oil drilling rigs.
