摘要： A fluid sensor (10) comprises a base member (20) defining a fluid flow path (21), a cavity filler member (26) located externally of the base member (20), and a cavity member (30) located externally of the base member (20) and the cavity filler member (26). The cavity member (30) is configured so as to provide confinement for an electromagnetic field. The base member (20) and the cavity filler member (26) are both configured so as to permit transmission of electromagnetic radiation at a frequency of the electromagnetic field therethrough. The electromagnetic field may be a radio frequency (RF) electromagnetic field. The base member (20) and/or the cavity member (30) may define an outer cavity region externally of the base member (20). The cavity filler member (26) may completely or partially fill the outer cavity region. The fluid sensor (10) may be used in the measurement of the composition and/or flow characteristics of a fluid in the fluid flow path (21).

摘要： A fluid sensor comprises a base pipe 320 defining a fluid flow path and a cavity member 330. The cavity member 330 comprises an electrically-conductive composite material including a matrix and one or more reinforcing elements like carbon fibres 374 embedded within the matrix. In one embodiment the carbon fibres 374 in the main body portion 330a of the cavity member 330 are wound along a left-handed helical path at an angle of approximately 80 degrees relative to the longitudinal axis 376 and along a right-handed helical path at an angle of approximately 45 degrees relative to the longitudinal axis 376. Such an arrangement of carbon fibres may permit omni-directional current flow in the main body portion 330a, which thus supports the same modes that would be supported by a metallic cavity member of the same geometry.

摘要： A fluid sensor includes a core defining a fluid flow path, a confinement member located externally of the core, and a patch antenna located between the fluid flow path and the confinement member. The confinement member is configured to confine an electromagnetic field which extends into the fluid flow path. The patch antenna is configured to couple an electrical signal to and/or from the electromagnetic field. The fluid sensor may be configured for measuring the composition and/or flow rate of a fluid and, in particular but not exclusively, for measuring the composition and/or flow rate of mixtures of oil, water and gas.

摘要： A fluid sensor comprises a fluid conduit having a wall defining a fluid flow path and an acoustic transducer located externally of the fluid flow path. The wall of the fluid conduit comprises a composite region between the acoustic transducer and the fluid flow path, the composite region comprising a composite material including a polymer matrix material and one or more reinforcing elements embedded within the polymer matrix material. Such a fluid sensor may be used for sensing a property of a fluid and, in particular though not exclusively for sensing a property of a fluid produced from or injected into an oil or gas well.
