ABSTRACT:
The flowmeter of the present invention comprises at least one conduit with the two extremities respectively connected to an inlet and outlet legs, an electromagnetic vibrator generating flexural vibrations of the conduit, and a motion detector detecting the flexural vibrations of the conduit, wherein the flexural vibration of the conduit has amplitude increasing from one extremity to the other extremity of the conduit. The media moving through the conduit carries away energy and momentum belonging to the flexural vibrations of the conduit and, consequently, attenuate the flexural vibrations at a higher rate compared with the flexural vibration of a conduit containing stationary media. The mass flow rate of media moving through the conduit is determined from the convective portion of attenuation of the intermittently imposed flexural vibrations, or from the convective portion of the decrease of the kinetic energy of the continuously imposed flexural vibrations.
