One of the main challenging measurement tasks is the determination of the crude oil, water and gas fractions in the offshore oil production. Out of the possible measurement principles electromagnetic interaction is promising for cases where the fluid components have distinct dielectric properties. In this paper a new type of non-invasive multiphase meter is described which is based on a radio-frequency dielectric measurement principle using a slow-wave resonator. The data analysis is based on a theoretical treatment of the metering system. By deriving an exact relation between the dielectric properties of the flow components and the resulting resonance spectrum the individual volume fractions can be obtained from the measuring data. The theoretical model is verified by experimental results. © 2004 Oldenbourg Wissenschaftsverlag GmbH Engineering: general nationallicence Instruments & instrumentation engineering nationallicence Materials science nationallicence Gasch Armin aut Riegler Peter aut Powell Steve aut tm - Technisches Messen/Sensoren, Geräte, Systeme Oldenbourg Wissenschaftsverlag GmbH 71/9/2004(2004-09-01), 486-491 0171-8096 71:9/2004<486 2004 71 teme https://doi.org/10.1524/teme.71.9.486.42757 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/teme.71.9.486.42757 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Gasch Armin aut NATIONALLICENCE 700 1- Riegler Peter aut NATIONALLICENCE 700 1- Powell Steve aut NATIONALLICENCE 773 0- tm - Technisches Messen/Sensoren, Geräte, Systeme Oldenbourg Wissenschaftsverlag GmbH 71/9/2004(2004-09-01), 486-491 0171-8096 71:9/2004<486 2004 71 teme CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
