Vacuum leak detector with an additional sensor for the detecting of occuring liquids in the manhole or bunds e.g. beneath the burner pump.
VL 34 E for tanks with leak protection lining with a suction line for the leak detector to the low point of the interstitial space.
VL 330 E for tanks without suction line.
VL 34 E, VL 330 E
P: weatherproof housing
M: digital manometer
S: service display (preset to 12 months)
Si: service indication (adjustable 1 to 63 months)
(e.g. VL 330 EPM)
- Maximum liquid pressure on tank bottom: <= 300 mbar
- Maximum internal overlay pressure: 500 mbar
- Underpressure resistance of interstitital space: for VL 34 E > -250 and for VL 330 E > -700 mbar
Water-polluting liquids with a flash point > 60 °C (for Germany > 55 °C acc. TRBS and TRGS) where no explosive vapor-air mixtures occur.
