Abstract

En fremgangsmåte og et apparat for å måle minst én parameter av at et fluid som strømmer gjennom en innvendig passasje av et langstrakt legeme er tilveiebrakt. Den innvendige passasje er anbrakt mellom en første vegg og en andre vegg, og den første og andre vegg vil hver omfatte en innerflate og en ytterflate. Fremgangsmåten omfatter trinnene med å tilveiebringe en rekke av minst to ultrasoniske følerenheter som overfører ultrasoniske signaler ved en eller flere frekvenser vesentlig sammenfallende med minst én frekvens ved hvilken de overførte ultrasoniske signaler resonnerer i den første vegg, mottar de ultrasoniske signaler med følerenhetene, og behandler de mottatte ultrasoniske signaler for å måle den minst ene parameter av fluidstrøm i den innvendige passasjen.
