Abstract
Separating drum 1 is provided with a device for determining the position, the composition and the nature of several layers of fluid settling upstream from barrier 8. The device comprises a first rod 12 provided with microwave beam emitters 13, a second rod 14 provided with microwave beam receivers 15, a microwave source 16 that can be connected to emitters 13, and means 17 for recording and analysing the microwave beams received by receivers 15.
Claims12
1) A device for determining the position, the composition and the nature of several superposed fluid layers, comprising:
- a separating drum containing at least two fluids arranged in superposed layers, the interface formed by the boundary between two layers being a horizontal plane, the drum comprising at least two microwave beam emitters arranged on a first rod and at least two microwave beam receivers arranged on a second rod, the first and second rods running through said plane, at least one of the emitters being arranged in one of the layers and at least one of the receivers being arranged in another layer,
- a microwave beam source that can be connected to the emitters,
- processing means for recording and analysing the microwave beams received by receivers and the microwave beam emitted by the source.
