Measurement Of Levels Of Liquids Or Fluent Solid Materials
(AREA)
Abstract
Liquid (24) level evaluator (42) consisting of a indicator instrument for the level (43), a light source (21), one or more hole evaluators (22) and a fibre optic (31-40) bundle (20) in between the light source (21) and the singular or multiple hole evaluators (22) passing in the liquid which the level reading if from. The bundle (20) includes fibres (10) that have been selectively cut off by a cut (11) angled perpendicular (9) to the fibre axis (19) equal or superior to the light incidence limit angle (14) that causes total reflection in the air. The light is carried by fibres (31-40) and evaluates the corresponding surveyors only when the cut (11) of each fibre is immersed in the liquid, thus determining a corresponding indicator on the evaluator (43).
Method and system for connecting glass fibers without Fresnel reflection, variable optical attenuator and system using the same for measuring the influence of the reflectance on an optical transmission path.
