Abstract
The present invention is a system permanently installing measuring sondes against the inner wall of a pipe (,) such as a well or a tube. Measuring sondes (,) are respectively associated with coupling devices (,) that are brought to their coupling points in the pipe by means of an elongate support element (,) such as a cable or a tube. Each coupling device (,) comprises a deformable element (,) made of a shape-memory alloy that is deformed in order to allow displacement thereof along the pipe, and that is brought back to its expanded (convex) shape for example by means of a hot fluid stream that is injected in the pipe by means of a pump (P). In this expanded position, it immobilizes coupling device (,) and presses the sonde (,) against pipe (,) while mechanically decoupling the sonde from support element (,). The support element may be withdrawn if not serving another purpose.
