摘要
The leakage monitor/indicator operates by an overpressure technique on double-walled storage tanks for water contaminating inflammable and non-inflammable liquids and for double-walled interconnecting piping. The individual leak indicators are maintained at a constant overpressure in the monitoring space between the inner and outer walls of the tanks and piping. Multiple leak indicators (4,2) for tanks (5) and piping (3) are supplied by pressurised gas source (7,6) consisting of a compressor or reservoir.
