ABSTRACT:
A mass flow meter for flowing media with equipment for determining the coriolis force consists of a helicoidally bent measuring tube provided with two tube loops whose inflow and outflow ends are fastened to a massive cast block and between whose oppositely pivotable tube loops are arranged an oscillator and two sensors measuring the torsional oscillations. For a more compact stiffening and an improved clamping of the measuring tube at the cast block, the two tube loops are in each case ovally bent in one plane, extend approximately parallel to one another and are provided on one longitudinal side in each case with two tube sections lying opposite to one another in an alignment line (x.sub.1 --x.sub.1 or x.sub.2 --x.sub.2). Of these sections, two are crosswise connected through a central tube part extending between the two loops and the two other tube sections are joined to the tube inflow and outflow ends which extend in opposite directions in a curved shape between the two tube loops and which run coaxially to the longitudinal sides to the outside. The tube loops are clamped and welded to the cast block in the area of these four tube sections.
