Abstract
This work describes the fiber optics sensors development for homogeneous or heterogeneous flows measurement. Optical sensors are distinguished from conventional sensors because they are coupled in optical fiber. The great advantage is immune to electromagnetic interference; Are made inert material (glass), little reactive and conducive to environments subject to explosions; Can potentially be read from a distance because of the low attenuation of the optical fiber; Are compact and durable. For all this the optical sensors have been applied in the industry in inhospitable environments or where another type of sensor can not be used. The optical sensors used are based on Bragg gratings in Fiber Bragg Gratings (FBG) and also in heterogeneous structures SMS and SMSMS formed by the splice between optical fibers of different technologies. The acronym SMS and SMSMS literally represent the order of the different fiber technologies in the formation of the hetero structure, with "S" being the designation for single mode fiber and "M" the designation for multimode fiber optics. This article presents a procedure for the design and application of new optical fiber sensors flow measurement. An innovative methodology is presented to design fiber optic sensor, and its application to speeds and flows measurement.
