Vacuum leak detector VLXE ..

THE FIRST FULLY ELECTRONIC PRESSURELESS TANK VACUUM LEAK DETECTOR FOR THE MONITORING OF EX-LIQUIDS

With its simple explosion-protected design, the VLXE is also suited, among other things, for the monitoring of ethanol-containing fuels. The assembly of the leak detector must always take place outside of an ex-zone. 

Type designation with alarm suppression in mbar:
• VLXE 34 M for tank with suction line to the low point of the interstitial space
• VLXE 330 M for tank up to 3 m diameter without suction line to the low point of the interstitial space
• VLXE .. M in higher pressure levels for tanks with larger diameters and/or higher stored goods as 1 g/cm3, e.g.
VLXE 500 M or VLXE 570 M 

Tanks that can be monitored (pressureless):
Pressureless tanks are tanks with a max. of 50 mbar of excess pressure (e.g. through recovery systems) for liquids with a flashpoint smaller/equal to 60 °C (for Germany it is smaller/equal to 55 °C). These may include:  
• single-walled lying cylindrical tanks with leak protection lining or coating
• double-walled cylindrical tanks 
• double-walled (and single-walled with leak-protecting lining/cladding) standing cylindrical tanks or tubs with curved  floors
• rectangular or cylindrical tanks or tubs with flat floors (fully double-walled or with leak protecting lining/cladding) 

Monitorable fluids:
• fluids hazardous to water
These possible vapour-air mixtures must be heavier than air and classifiable into Gas groups IIA to IIB3 as well as Temperature codes T1 to T3. 

Stored goods:
e.g. diesel, petrol, ethanol-containing fuels 

Versions:
Brass or stainless steel (VA-V) 

Equipment options:
• Digital pressure indicator M
• Service indications
• Remote monitoring LOD (LE = Leak Detector of Online Diagnostics with Ethernet) 

Accessories:
• Protective roof
