The invention relates to a fluid separating device comprising a lower section which is provided with a fluid feeding device and a device for removing liquid, an upper section which is provided with a fluid feeding device and a device for removing gas, a contact device which is constructed in such a manner that gas, which exits the lower section and rises to the upper section, comes into contact with the liquid which exits from the upper section and falls into the lower section. The rising gases can be depleted with regard to components which are soluble in said liquid. Said fluid separating device also comprises a measuring device for determining the quantity of liquid and/or the alterations thereof.
