FIBER-OPTIC LEVEL GAUGE-PRESSURE INDICATOR Russian patent published in 2019 - IPC G01F23/22 G01L7/06 G01L7/08 

FIELD: monitoring and measuring equipment.

SUBSTANCE: device relates to instrumentation and can be used for discrete measurement of liquid level or pressure, including opaque, in conditions of high spark, explosion and fire hazard, exposure to vibrations, shocks, ambient temperature variation in the range of (-100...+150) °C (and more) on items of aviation, rocket and space, marine equipment, oil and gas industry. Fiber-optic level gauge-pressure indicator comprises radiation sources and receivers, supply and discharge optical fibers, sensitive elements in the form of round cross-section rods with spherical segments of optically transparent material, located in the housing, the number of which is equal to the number of information acquisition points, as well as elastic element made in the form of bellows or membrane, separating sensitive element from liquid, longitudinal axis of which coincides with longitudinal axis of rod, inner diameter of which exceeds rod diameter, hermetically connected from one end to housing, the other end of which is blind.

EFFECT: technical result is possibility of fixing level or pressure of any type of liquid in required points of reservoirs.
