<p>A flowmeter (1) comprising two U-shaped coplanar tubes (2, 3) carrying an upstream fluid ( PHI 1, PHI 2); a body (4) inside which the ends of the tubes (2, 3) are fitted; first means (27) for oscillating the tubes (2, 3) at their resonance frequency about an axis (A-A) defined by the points at which the tubes (2, 3) are fitted to the body (4); and second means (32, 33) for determining the tilt angle of central portions (5, 6) of the tubes (2, 3) opposite the body (4). From each central portion (5, 6), there originate two lateral arms (7, 11 and 8, 12); the arms (7, 11) of the first tube (2) respectively defining an obtuse and an acute angle with its central portion (5), and the arms (8, 12) of the second tube (3) respectively defining an acute and an obtuse angle with its central portion (6). <IMAGE></p> |
