A valve box having a metallic riser and a metallic lid covering a top of the metallic riser and an electromagnetic resonator coupled to the valve box interior facing side of the metallic lid, whereby, upon generation of an eddy current in the metallic lid, a current is generated in the electromagnetic resonator. This valve box, when buried, is readily locatable and identifiable by an above-ground interrogating device.

A cathodic protection monitoring system for buried metal objects comprising a transponder hard-wire connected to a sacrificial anode and a reference electrode, each of the transponder, the sacrificial anode and the reference electrode being buried underground in close proximity to the buried metal object to be protected, thereby forming a first principal circuit between the sacrificial anode and the buried metal object and forming a second principal circuit between the reference electrode and the buried metal object. The system further comprises a portable transceiver disposed above ground tuned to a frequency of the transponder. Power for operation of the transponder is drawn from the cathodic protection circuit, thereby obviating the need for connections to above ground power supplies.

Remote cathodic protection monitoring system

The presence and flow of water or other liquids in pipes, such as gas pipes, is observed by viewing through an opening in the pipe. A colorant liquid which disperses in the liquid is inserted into the pipe and an illuminating element such as an chemiluminescent device is positioned in the pipe at the site of suspected liquid.
