Measuring transducer having a securement element and an add-on part on the flow tube acting as a cancelling mass

A Coriolis mass flow meter, comprising:

• a measuring transducer of the vibration type, comprising:
• a housing:
• and
• a mass flow tube, wherein:
• said mass flow tube is formed into a helix including a first loop and a second loop;
• said mass flow tube includes a securement element, which affixes a peripheral point of said first loop relative to a neighboring peripheral point of said second loop;
• said mass flow tube includes an oscillation exciter on a side lying opposite said securement element along said mass flow tube;
• and
• said mass flow tube includes between said oscillation exciter and said securement element at least one add-on part acting as a canceling mass, said add-on part is secured to exactly one of said first and second loops for suppressing undesired torsional moments, which act around a rotation axis imaginarily connecting the securement element and the oscillation exciter.
