For monitoring tanks
For tanks at petrol stations, pressure leak detectors offer the optimum benefit-cost ratio. Several tanks with a leak detector can be monitored safely and cost-efficiently using the DL 330 range of leak detector systems.
For monitoring pipes
Pipes at petrol stations with a pressure system (submersible pump in the tank) are monitored using an explosion-protected underpressure leak detector (VLX 330 A-Ex).
