Abstract
In a pipeline fluid tagging system, an RF transmitter enclosed within a sealed housing is immersed in one or more of the fluids being transported, and transmits information pertaining to that fluid, such as its type, destination and quantity. One or more receivers, preferably located around the joints between lengths of the pipeline receives the RF signals and communicates them to a data collection facility either by a separate RF transmitter or along land lines. To avoid damage and wear, the transmitter housing is formed into a shape that minimizes contact with the inner wall of the pipeline. This shape is used in conjunction with passive and active mechanical stabilization techniques to further ensure that the transmitter maintains its orientation along the longitudinal center line of the pipe.
