FIELD: physics.
SUBSTANCE: invention relates to a combined optical system for recognizing a container and a filling level. System comprises at least one removable container (14, 114, 214, 314) with inner cavity (32, 332) for receiving fluid or granular media (34, 334) and at least one container receptacle (12, 312) for container (14, 114, 214, 314). Container receptacle (12, 312) is provided with reflection light barrier (22, 122, 322), wherein container (14, 114, 214, 314) comprises body (36, 336a, 336b, 336c, 336d) of immersion in form of light guide, which projects into medium (34, 334) and is optically connected to the reflection light barrier (22, 122, 322), if the container in container (12, 312) is in the measurement position. For optical connection to reflecting light barrier (22, 122, 322) immersing body (36, 336a, 336b, 336c, 336d) at one end comprises light emission input plane, which is located on surface of container (14, 114, 214, 314) and in certain specified position of container (14, 114, 214, 314) in container (12, 312) is located opposite light emission exit surface of light barrier (22, 122, 322) of reflection. At the other end of immersing body (36, 336a, 336b, 336c, 336d) there is a wetting plane configured to change its reflecting action if wetted by the medium.
EFFECT: invention simplifies measurement of level of filling and recognition of container.
