<p>The detector has a channel (1) receiving fluid. A mobile body (3) i.e. ferrite rough block, is moved under a fluid effect and includes a part magnetizable material. A detecting unit (7) detects presence of a magnet. The body has a cylindrical side surface along which the fluid flow. An upstream portion (22) of the channel extends axially with respect to the body in the upstream position. The channel has a downstream barrier (23) located downstream from the upstream portion and opposite to a part (24) of the side surface of the body when the body is in a position extreme downstream (6). An independent claim is also included for a method for adjusting hysteresis of a fluid flow detector.</p> |
