Zusammenfassung:The device has a mobile rotary element (3) and a fixed bearing-forming element (2) solidly connected to an upstream end of a tube (1). The mobile element comprises an upstream trunnion-forming part (4) and a downstream turbulence-generating part (5) which is rotated by the flow of the fluid in the tube. The upstream and downstream parts are connected with respect to each other using a flexible connector (6) deformable along entire length. The connector is made of stainless steel, plastic, carbon fiber, synthetic fiber or elastomer.
