An integrated leak detection system for a rotating union provides improved leak detection and user convenience. In an embodiment of the invention, the system provides a leak detection sensor located within the union, and in an embodiment of the invention the detection sensor is located beyond a back-up seal system. In an embodiment of the invention, the sensor and processing electronics are integral to the union housing. In yet another embodiment of the invention, the detection sensor is substantially symmetrically configured to detect leakage into a protected area regardless of orientation of the union. In an embodiment of the invention, the fluid being conveyed is electrically conductive and the detection sensor comprises an electrical conductivity sensor. |
