Abstract
The invention relates to a device for controlling the pressure within a pulsed column. The device comprises first and second dipping tubes respectively issuing into the column at the level of points P.sub.1 and P.sub.2, means for introducing a gas into each of the tubes and for bubbling it in the column liquid and means for determining the pressure difference between said tubes. The first and second dipping tubes respectively issue into the column via cavities C.sub.1 and C.sub.2 having dimensions such that during pressure variations due to pulsation, the gas-liquid interface is always located in each of said cavities and the variations in the gas-liquid interface level in each cavity are inversely proportional to the densities of the liquids present in each cavity. Thus, it is possible to eliminate the prejudicial influence of pressure variations within the liquid due to pulsation. The device can in particular be used for measuring the interface level in the decanter.
