Abstract

Abstract Title: Resonant cavity fluid sensor. A fluid sensor comprises an enclosure 36 that defines a microwave resonant cavity and an electrode 50 located within the cavity, which is configured to generate a varying electromagnetic field within the cavity. The resonant cavity has a sensing end comprising end wall 42 with an aperture or window 44 through which a fringing electromagnetic field 58a can extend from the cavity into a fluid 56 located adjacent the cavity sensing end. The cavity has a cross-sectional area A at the sensing end and the window has an area Aw that is less than the cross-sectional area A. The fluid sensor may sense the water content of a multiphase fluid located adjacent the sensing end, perhaps in a pipeline. A dielectric window material may cover the aperture 44. Fluid level, film thickness, moisture in a gas, and fluid presence may also be sensed.
