Abstract

En fremgangsmåte for å bestemme en innbyrdes avstand mellom to objekter i en rørledning er beskrevet. Fremgangsmåten omfatter følgende trinn: å forsyne en rørledning som er forsynt med et medium som har en akustisk impedans som er forskjellig fra den akustiske impedansen til materialet i rørledningen og/eller et medium som er tilstede utenfor rørledningen; å forsyne hvert av de to objektene med en klokke; å synkronisere klokkene; periodisk å sende et akustisk signal fra et første til et annet av de to objektene; å måle mottakelsestidspunktet for det akustiske signalet; å bestemme forsinkelsestiden fra det første til det andre objektet; og å beregne en tilbakelagt distanse for signalet mellom de to objektene på grunnlag av en forplantningshastighet for det akustiske signalet i mediet og den målte forsinkelsestiden til det akustiske signalet.
