Abstract

Oppfinninga omfattar innretning for måling av refleksjonskoefisienten til høgfrekvente elektomagnetiske bølgjer i væsker og fleirfase strøymings- reskime. Innretninga er utforma som ei open-ende probe, for måling av refleksjonskoeffisienten, i eit lokalt område nær proba si endeflate. Proba er spesielt konstruert med tanke på det høge trakket'og den høge temperaturen som er vanleg i eit produksjonsrørTor olje.The invention includes apparatus for measuring the reflection coefficient of high frequency electromagnetic waves in liquids and multi-phase flow regimes. The device is designed as an open-end probe, for measuring the coefficient of reflection, in a local area near the probe's end surface. Proba is specially designed for the high traction and high temperature common in a production oil tor.
