Abstract
A device (30) for sensing fluid behavior, e.g. flow, in a conduit (34) such as downhole in a well, comprises a tool (36) having two or more spaced sensors (38,40) for interacting with a medium within the conduit to produce data signals. The sensor data signals may be compared to determine movement of the medium within the conduit and about the device. The device is particularly suited for determining movement of multi-phase fluid.
