Abstract

Metode og apparatur muliggjør direkte måling av minst én strømningshastighet for én eller flere faser inne i en flerfase fluidblanding som strømmer i en ledning. Noen utførelsesformer tilveiebringer bestemmelse av sanntids individuelle fasestrømningsmengder for tre faser (f.eks. olje, vann og gass) som er distinkte fra hverandre i fluidblandingen. En flerfasestrømningsmåler ifølge utførelsesformer av oppfinnelsen inkluderer i det minste to optiske følere romlig fordelt langs en lengde av ledningen og konstruert til å detektere lysvekselvirkninger med fluidblandingen spesielle for fasene, slik at detekterte tidsvarierende signaler kan bearbeides via krysskorrelasjon eller en ordnet systembearbeidingsalgoritme til å tilveiebringe ønsket individuell fasestrømningshastighet for olje-, vann- og/eller gassfasene. Denne strømningshastighet kan anvendes for fasefraksjonsmålinger, som kan oppnås ved anvendelse av den samme strømningsmåler og en ytterligere separat innretning, for å beregne strømningsmengdene for fasene.
