FIBRE-OPTIC LEVEL GAUGE AND METHOD OF MAKING SAID GAUGE Russian patent published in 2015 - IPC G01F23/22 

FIELD: physics.

SUBSTANCE: fibre-optic level gauge, comprising radiation sources and detectors mated with input and output optical fibres, respectively, stretched through a pipe with through-holes on the lateral surface, rigidly mounted on the housing pipe, consisting of interconnected pipes, bushings with a through-hole, ferrules in which are mounted circular bars with a spherical segment made of optically transparent material, wherein the holes of the hollow pipes are aligned with holes in the pipe; the number of holes, housings and bars corresponds to the number of points for reading information about the level of liquid; the longitudinal axes of the housings are straight; the axes of the pipes and housings lie at an angle less than or equal to 90 degrees; the ferrules are in the form of a cylinder and a truncated cone, wherein the cylinder is the base of the truncated cone, the small base of which faces the spherical segment of the bar. The present invention also provides a method of making a fibre-optic level gauge.

EFFECT: improved manufacturability of the fibre-optic level gauge, simple assembling process and high reliability.
