Abstract

Oppfinnelsen gjelder en fremgangsmåte og en anordning for måling av en elektrisk egenskap hos fluid som strømmer gjennom et rør, og der anordningen omfatter minst: en første måleelektrode og en andre måleelektrode, anordnet i rommessig kontakt med røret, der den første måleelektrode opptas i et legeme anordnet i rørets innervegg, og der denne første måleelektrode er skilt fra rørets innervegg med et gap som strekker seg over i det minste en del av rørets innerveggs omkrets. Som et resultat av disse tiltak reduseres avstanden mellom måleelektrodene vesentlig, slik at målenøyaktigheten bedres betydelig. Målekretsen er fortrinnsvis innrettet for gjentatt suksessiv måling av motstandsverdien og kapasitansen av fluid.
