The present invention provides a monitoring system (16) for a conduit network including one or more conduit sections (30, 38) joined at one or more conduit nodes (40-48), including: one or more sensor devices disposed at selected ones of the one or more conduit nodes, wherein each of the one or more sensor devices is operable for sensing a blockage or breakage (50) in an associated conduit section (30), and wherein each of the one or more sensor devices is operable for communicating blockage or breakage information to a central location. Optionally, each of the sensor devices includes one of an audio sensor device and a radio frequency sensor device. Each of the sensor devices is operable for sensing the blockage or breakage in the associated conduit section by measuring an attribute of a transmitted/received signal, alone or in combination with another sensor device. Each of the sensor devices is operable for communicating the blockage or breakage information to the central location via a wireless link. |
