FIELD: engineering of devices for controlling integrity of construction, positioned in surrounding environment, containing liquid substance under pressure from surrounding environment.
SUBSTANCE: construction includes cover and set of internal hollows. Method for controlling includes feeding liquid substance into hollows, while fed liquid substance is under pressure, which is severely greater, than pressure of surrounding environment. Speed of stream (flow) of fed liquid substance is controlled. Alternation of speed of stream (flow) is a coefficient of additional loss of flowing substance through construction, which allows to output alarm signal about disruption of its integrity beforehand. Control is performed, letting through fed liquid substance through large full resistance to liquid substance and controlling by means of indicator the alternation of pressures change at full resistance.
EFFECT: prevented moisture influx inside construction.
