Abstract

Opfindelsen vedrører en fremgangsmåde til detektering af lækager i rørinstalla tioner med fremløbs- og returløbsledninger ved hjælp af et lækagesikringssystem (1), som omfatter dels mindst en afspærringsventil (2) med tilhørende elektrisk aktuator (9) og en flowmåler (3) anbragt i rørinstallationens fremløb (4), dels mindst en afspærringsventil (5) med tilhørende aktuator (9) og en flowmåler (6) anbragt i rørinstallationens returløb (7), hvilke afspærringsventiler (2,5), aktuatorer (9), og flowmålere (3,6) er forbundet til en kontrolboks (8). Kontrolboksen er indrettet til afvikling af fremgangsmåden ved gennemløb af et periodisk forløb, som omfatter en måle- og aktivitetsperiode efterfulgt af en mak tiv periode, og hvor måle- og aktivitetsperioden omfatter - opsamling af flowdata fra fremløb (4) og returløb (7) med de tilhørende flowmålere (3,6), - registrering af tilstedeværelse af luft i fremløb (4) og returløb (7), - behandling af de opsamlede flowdata i et regneværk, - registrering af driftsforstyrrelser ud fra de behandlede flowdata og - beslutning om indgreb ud fra antallet af registrerede driftsforstyrrelser, hvis an tallet af driftsforstyrrelser overskrider et fej (B), idet fejikriteriet (B) lø bende korrigeres i overensstemmelse med antallet af luftindikationer. Opfindelsen vedrører yderligere et lækagesikringssystem til udøvelse af frem gangsmåden. Herved anvises en fremgangsmåde og et lækagesikringssystem, som også tolererer ultralydsmåleres adfærd, uden at systemet afgiver falske alarmer og uden at mindske systemets 4
