Apparatus for determining the position of a leak signal from a pipe

摘要

An apparatus for determining the position of a signal from a pipe (1), the apparatus comprising a first sensor (9) capable of being coupled to said pipe for detecting a signal from said pipe (1), a second sensor (13) being moveable with respect to said pipe (1) for detecting a signal from said pipe (1) and determining means for determining a variation between the signals detected by the first (9) and second (13) sensors, due to the differing position of the first and second sensors with respect to the pipe (1).
