Claim:
1. A fluid measurement system for measuring moving fluid along a length of a conduit comprising: an elongate structure physically divided into a plurality of sampling sections along it's length and located in the conduit; a heated core element and a distributed temperature sensor along the length of the structure, said heated core element and said distributed temperature sensor arranged so that the temperature sensor is physically between the heated core and an outside surface of the structure to sense heat loss from the core to its environment, and said heated core element and said distributed temperature sensor are encased in a material which thermally isolates the heated core element from the moving fluid; one or more wires arranged along the length of the structure, said wires being configured to be usable as a transmission line; at least one high frequency pulse generator for injecting a high frequency pulse along at least one sampling section of the structure; and a data acquisition unit for recording the heat loss along the distributed temperature sensor and the velocity of the high frequency pulse along each sampling section of the structure to provide a two-dimensional measure of fluid type and velocity simultaneously for the length of the conduit.
