ABSTRACT:
The present invention relates to a device making it possible to detect variations in the height of the free level of a liquid in an enclosure.
The device comprises a vertical short tube issuing into the upper part of the vessel and whose upper end issues into a first condensation pot, a long tube whose long end issues into the vessel at a level below that at the end of the short tube, the end of the long tube being provided with a hydraulic seal, while the upper end of the long tube issues into a second condensation pot, a differential manometer indicating any pressure differences between the two condensation pots.
Application to the measurement of the level of the water contained in the vessel of a pressurized water nuclear reactor.
