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 and a single tube section that connects the adjacent ends of the measuring loops. Tubular 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. Two blocks have tube holder portions for having the tubular section and the measuring loops opposite ends adjacent their juncture to the resilient portions and the attachment portions adjacent their juncture to the resilient portions respectively extended therethrough. The measuring loops are oscilatable in the opposite direction 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.
