Abstract: A combined method and apparatus for the detection, monitoring and control of electrolytic corrosion in pipelines and other metallic structures along with pipeline valve status and pressure changes indicating a loss of flammable or toxic high pressure products. Pipeline valve station and corrosion protection station status is monitored and controlled from a distant location. The apparatus transmits data by electrical signal along the conductive pipe or by short-range and long-range radio transceivers.

Abstract: Several remote monitoring stations along a corrosion protected pipeline or structure are served by a single long range radio transceiver link to a central data collection station. Individual monitoring stations are in cost-free, short range communication with each other, while a single central module has an additional longer range, paid subscriber transceiver. The number of paid subscription links by cellular or satellite services to remotely monitor corrosion protection voltages and currents are substantially lessened by this combination.

Abstract: A system comprises a plurality of instruments for gathering data and a network of mesh nodes communicably coupled to the plurality of instruments, the mesh nodes for obtaining the data from the instruments. The system also comprises a concentrator mesh node. The network of mesh nodes transmits the data to the concentrator mesh node while the concentrator mesh node is airborne. The concentrator mesh node receives the data and, when the concentrator mesh node is no longer airborne, the concentrator mesh node transfers the data to a destination via a network.
