ABSTRACT:
A single tube parallel flow Coriolis mass flow rate sensor including a single continuous tube folded upon itself in a generally elongated helically looped fashion so that a straight input segment of the loop is positioned in parallel to a straight output segment and the fluid flowing through the loop flows in the same direction in both segments. The extremities of the two straight segments are rigidly joined together and affixed to an enclosing housing. An oscillatory drive mechanism is coupled between the straight segments at their mid-points and a pair of sensing mechanisms are coupled between the tubes at points intermediate the respective ends and their mid-points.
