Abstract
An apparatus for non-intrusively sensing fluid flow within a pipe is provided. The apparatus includes an array of sensors that include a plurality of optical fiber coils. The array of sensors senses the fluid flow inside the pipe. At least one optical reflective device is disposed between adjacent optical fiber coils. An isolation pad is disposed between each optical reflective device and the pipe.
Claims25
An apparatus for sensing fluid flow within a pipe, comprising:
- a sensing array for sensing fluid flow within the pipe, the sensing array having a plurality of optical fiber sensors;
- at least one optical reflective device disposed between adjacent sensors;
- and
- an isolation pad disposed between the optical reflective device and the pipe.
A sensing apparatus, comprising:
- a fiber optic sensor mounted on an outer surface of a conduit;
- and
- an isolation pad disposed between the sensor and the conduit outer surface,
- wherein the isolation pad isolates the sensor from expansion or vibration of the conduit.
A method for constructing an apparatus for sensing fluid flow within a pipe, comprising:
- positioning a fiber optic sensing array comprising a plurality of sensors around the pipe;
- coupling a fiber optic reflective element between adjacent sensors;
- and
- positioning an isolation pad between the fiber optic reflective device and the pipe.
