摘要：
An assembly for detecting and measuring the fouling rate by deposits containing at least one ferromagnetic material, including a probe which can be continuously moved inside a tube and which has a body carrying on its outer surface at least one magnetized source for self-orientation of the body of the probe, at least three magnetic field emitters and at least three magnetic field detectors each positioned between two contiguous emitters.
