Abstract
The invention is a device for separating a mixture of fluids (conducting fluid, non-conducting fluid, gas), suited to measure the volumes of the various fluids by means of a capacitive measuring process. The invention comprises a unit (WOS) for separating a conducting liquid phase and another, non-conducting liquid phase or non-conducting gas phase that's immiscible with said first phase along an intervening interface, comprising an elongate tubular vessel (T) whose outer wall (1) is made of a conducting material and whose inner wall (2) is made of an insulating material, this vessel being arranged vertically in operation, a conducting element (3) in contact with the conducting first phase, that can be combined with a second unit (GOS) for separating a non-conducting liquid and a gas, comprising a second elongate tubular vessel (12) made of a conducting material placed above the first unit, an elongate electrode (14, 15) arranged substantially in line with the second vessel and electrically insulated therefrom a capacitance measuring unit (8) that is connected by conductors (LI-L4) to conducting element (3), to the outer wall (1) of the first vessel, to second vessel (12) and to el…
