FIELD: automobile, petrochemical industries, inspection of quality of oil products. SUBSTANCE: gear includes flask 1, heater 8, temperature meter, heating regulator 12, actuator 13, unit recording measurements of fuel level incorporating transmitting 2 and receiving 3 surface microinhomogeneous fibre- optical elements, light source 9 and device 10 determining amount of fuel. Transmitting 2 and receiving 3 elements present bare fibre-optical sections of equal length or fibre-optical sections with stripped off protective sheath. Butts of elements reflect light. Temperature meter includes temperature transducer 7 and radiating-receiving device 11 registering temperature. Temperature transducer 7 presents fibre of monocrystalline sapphire with light reflecting butt made from iridium and aluminium oxide. Transmitting element 2, receiving element 3 and temperature transducer 7 are placed into metal tube 4 having radial holes. EFFECT: increased functional reliability and accuracy. 1 dwg, 2 tbl
