SYSTEM FOR SUPPLY OF LIQUID WITH ACCURATELY SPECIFIED CONTINUOUSLY CONTROLLED PRESSURE Russian patent published in 2014 - IPC G01N15/14 

FIELD: machine building.

SUBSTANCE: control of fluid medium flow characteristics includes configuration that determines an internal chamber, the first fluid medium flow channel, the second fluid medium flow channel, a flexible partition, located between the first fluid medium flow channel and the second fluid medium flow channel, a fluid medium flow deviation sensor sensing the flexible partition movement under action of the first fluid medium flow, a fluid medium flow deviation signal generated with the fluid medium flow deviation sensor considering movement of the flexible partition. Besides, the control includes an analyser of fluid medium flow deviation signals, which can generate a corrective value of the second fluid medium in response to a fluid medium deviation signal, a correcting element for supply of the second fluid medium, a controller of the second fluid medium, which has a possibility of correcting characteristics of the second fluid medium flow entering the control through one or more inlet holes in the second fluid medium channel based on second fluid medium supply corrective values.

EFFECT: improvement of a system.
