    摘要: Disclosed is a probe for use in a fluid pipeline, comprising: a transmitter for transmitting an RF signal via an antenna (50); a receiver for receiving an RF signal via an antenna; a processor operable to compare the received signal with an expected signal. Also disclosed is a method of assessing the condition of a pipeline by means of a probe located inside the pipeline, comprising the steps of: transmitting an RF signal from the probe; receiving an RF signal at the probe; comparing the received and an expected signal and, based on the result of the comparison, indicating that the pipeline is acceptable or not.
