VLXE 34 M for tanks with a suction line to the low point of the interstitial space.
VLXE 80 M for tanks with separate chambers for diesel and petrol. A VLXE 80 M with a higher underpressure must be connected to the petrol leak protection lining to ensure that in case of a leak in the area of the chamber wall vapors are drawn in the direction of the Ex leak protection lining and not vice versa.
VLXE 330 M for tanks without a suction line to the low point of the interstitial space, up to 3 meters diameter, and a density of the stored product of <= 1 g/cm3.
VLXE 500 M and VLXE 570 M for tanks with larger diameters and/or higher densities of stored products of 1 g/cm3.
Service indication (Si)
Remote monitoring LOD with Ethernet module (LE)
- Horizontal cylindrical tanks with a maximum diameter of 3 meters
- Pressureless or with slight overpressures of a maximum of 50 mbar through gas recirculation systems at filling stations
- Underpressure resistance of interstitial space: VLX 34 M > -250 and VLXE 330 M > -700 mbar
Petrol and ethanol-containing fuels, diesel, kerosene, etc. Vapors must be heavier than air!
If the flash point of the liquid to be monitored requires explosion protection measures, the VLXE .. M can only be used on pressureless tanks.
Otherwise the VLXE .. M can also be used on tanks with up to 5 bar overpressure. The international hazardous substances law sets a limit of > 60 °C. National regulations may vary, so Germany > 55 °C.
