ABSTRACT:
In a flow meter that works on the Coriolis principle there is provided a single tube that is bent to have two measuring loops. Upper and lower tube attachment end portions are respectively connected through resilient tubular portions to the opposite ends of the two loops and may be part of the single tube. The loops are superposed and from the juncture of the loops and through at least parts of the attachment end portions are of a continuous downward gradient such that the fluid column in the flow meter will divide and drain through the attachment end portions. Two blocks have tube holder portions for retaining the loop first ends and the measuring loops opposite ends in vertical spaced relationship and connecting the attachment end portions together. The measuring loops are oscilatable in opposite directions while sensors are provided adjacent to the measuring loops for measuring the relative movement of the loops relative to one another to provide a measurement of the fluid flow through the loops.
