Method and apparatus for measuring mass flow

Coriolis type apparatus for measuring mass flow of a fluid stream

A conduit having two substantially parallel, flexible and continuous flow tubes fixedly mounted at their ends to a centrally positioned housing The ends of each flow tube positioned proximal to one another and to the center of gravity formed by the shape of the flow tube. Each flow tube substantially forming a 'B' shape having a first loop, a connecting portion and a second loop. The first and second loops being symmetrical with respect to the connecting portion and extending laterally from the center of gravity at a greater distance than the displacement of the connecting portion to the center of gravity. The flow tubes being oscillated in opposing modes at the connecting portion so as to produce a measurable Coriolis reaction force by the fluid on the flow tubes. The vibration means being capable of selectively oscillating the flow tube at least one discrete resonant frequency higher than the fundamental resonance of the flow tube so as to create waves along the tube length and form nodal points which are substantially stantionary with respect to the vibrating flow tube. The nodes form free floating flexible joints within the continuous flow tube to separate the oscillation of a portion of the flow tube partially from the fixed mounting points which are typically subject to unwanted vibrational noise.
