Abstract

Process and device for controlling the level of a liquid contained in a housing (1). A housing contains a condensor (8) in which a gaseous fluid is introduced. When the condensor dips into the liquid, the fluid is condensed and it is the pressure of the contained fluid which actuate the control member for controlling the liquid level.
