Title:
DEVICE FOR MEASUREMENT OF CHARACTERISTIC REFLECTION COEFFICIENT FOR ELECTROMAGNETIC WAVES IN MULTIPHASE FLOUR
Document Type and Number:
WIPO Patent Application WO1999042794
Kind Code:
A8
Abstract:
The invention includes a device for measuring the reflection coefficient of high-frequency electromagnetic waves in fluids and multiphase flow regimes. The device is designed as an open-ended probe for measuring the reflection coefficient in a local area near the terminal surface of the probe. The probe is designed taking particular account of the high pressures and the high temperatures common in oil production tubings.
