Abstract

Forskjellige strømningsmålere (10; 70; 80) har hver minst en NMR-føler (12; 72; 82) for måling av de forskjellige strømningsparametere for et strøm- mende fluid. NMR-føleren kan benyttes for å tilveie- bringe et gradientmagnetfelt som tilvciebringer separate hastigheter når fluidet er et flerfasefluid (fig. 10). Strømningsmålerne kan også benyttes til å måle strømningsmengde direkte. Strømningsmålerne kan også benyttes til å bestemme de separate strømnings- fraksjoner av et flerfasefluid.
