| 摘要 | This invention relates to a system of identifying and providing information concerning hidden pipelines, cables, ducts, passages etc. In Figure 1 a pipeline 10 is located below ground level 11 and has on it an information containing element which is interrogatable, and is clipped into a recess 13. An alternative is to have the element in the form of an inertly packaged coded tag 12A attached to the pipe by straps. A transmitter/receiver 14 is connected by a flexible cable 15 to an antenna 16. The transmitter/receiver has a power supply 17 and display 18. Connected to the transmitter receiver 14 is a decoder 19 and a recorder 20. On interrogation, the interrogatable element 12 responds and returns a signal which is picked up by the antenna 16 and supplied to the transmitter receiver 14 where it is decoded and recorded and also displayed on the display 18. Information displayed may provide details as to depth and direction of alignment of the pipe 10, the material of which it is made, the fluid which is flowing through it, etc. | ||||||
