Summary

S E R V I

- the probe can „see through” the KMPVC pipe (as well as the asbestos cement pipe), - the applied measurement parameters were appropriate (f = 1 kHz, Ls = 18 cm, Lc = 2 cm), - ferromagnetic materials had positive anomalies, diamagnetic substances had negative anomalies (iron, steel (+), copper, lead (-), -Objects smaller than Ls basically caused the same extent of anomalies, -Objects larger than Ls appear with actual thickness, - anomalies are independent of traction speed,

C E

- another possibility is the application of the CTD method using similar principles.
