Device and method for performing distributed fluid velocity measurement. An elongate device comprising along its length, a heated core (200), at least one outer layer (240) around the core, the outside surface of the outer layer (240) defining an outside surface of the device, and a distributed temperature sensor (230) located between the heated core (200) and the outside surface of the device. The method immerses the device in one or more fluids along its length, measures the ambient temperature of the fluids at points along it's length, heats the heated core (200) for a predetermined heating period and measures the temperature again at the same points. Using pre-installed knowledge the device can obtain distributed and/or point fluid velocity measurements. |
