Abstract:
1. A device for determining information about superposed fluid layers, comprising: a separating drum containing at least two fluids arranged in superposed layers, and an interface formed by a boundary between two of the superposed layers being a horizontal plane, the drum comprising at least two microwave emitters arranged longitudinally along a first device and at least two microwave receivers arranged longitudinally along a second device, the first and second devices running through the horizontal plane, at least one of the microwave emitters being arranged in one of the superposed layers and at least one of the microwave receivers being arranged in another layer of the superposed layers; a microwave source which is selectively connectable to the at least two microwave emitters to couple microwaves thereto; and a processor for recording and analyzing microwaves received by receivers and microwaves provided by the microwave source to determine the information about the superposed fluid layers.
