FIELD: machine building.
SUBSTANCE: device consists of tubular case inside of which there moves controlled medium, of vortex flow rate metre, of analyser of flow rate signal spectre, and also of individual indicator of gas bubbles in controlled flow consisting of exciting coil fed with alternate current and of measuring coil connected to signal converters. The exciting coil is made in form of a transit coil secured of a pipeline before the flow rate metre. The measuring coil is made in form of two similar opposite connected transit coils arranged on the case at equal distance from the exciting coil on opposite sides from it.
EFFECT: reliable control of break of pressure tightness of steam generator and of dynamics of leak development for on-line evaluation of equipment condition and for making decision for shut down.
