The Energetic Estimate of Optical Fiber Measuring System for Determination of the Fluid Composition

The authors suggests the losses estimate of the optical path of the optical fiber measuring system (FOMS) by the energetic estimate method. A calculated scheme is developed, the total losses of the optical path are determined, which depend on the number of measuring channels, the losses introduced by each individual optical element of the system are determined. This made it possible to select optical fiber components of the measuring system and meet the conditions of spark-explosion-fire safety.
