Abstract
Oppfinnelsen vedrører i en utførelse en fremgangsmåte eller anordning for å måle strømegenskapene i en flerfase fluidstrøm som strømmer i en rørledning som omfatter midler for prøvetaking med en prøvetaker, av en del av fluidstrømmen; for å måle et differansetrykk mellom et første trykk i fluidstrømmen i rørledningen og et andre trykk i prøvedelen av strømmen i prøvetakeren; for å styre strømningsraten i prøvedelen, hvor strømningsraten i prøvedelen styres for å tilveiebringe utnulling av differansetrykket for å oppnå hovedsakelig isokinetisk prøvetaking av fluidstrømmen; for å måle egenskaper i delen av fluidstrømmen; og for å behandle de målte egenskapene for å bestemme strømegenskapene til flerfasestrømmen som strømmer i rørledningen, hvor de ovennevnte elementene ikke krever eller utføres uten bestemmelse av tettheten av fluidet i fluidstrømmen ved hjelp av kjernefysiske strålingsmetoder. 1
