Method and measuring device for determining a fluid quantity

A measuring device for determining a fluid quantity relating to a fluid or a fluid quantity of a fluid flow of the fluid, the measuring device comprising:

• a control device;
• a measuring tube for receiving at least one of the fluid or through which the fluid flows;
• and
• a first and a second oscillation transducer being disposed at a distance from one another on said measuring tube and each having a plurality of mutually separated excitation regions, wherein said control device is configured to drive at least one of said first or said second oscillation transducer in order to excite a respective total wave, which is conducted through a wall of said measuring tube, by wave components which are respectively conducted in said wall being excited by said first and said second oscillation transducer by said plurality of mutually separated excitation regions of each of said first or second oscillation transducers, the wave components being superposed to form the respective total wave, wherein a distance between centers of the excitation regions and an excitation frequency is selected in such a way that an oscillation mode to be attenuated is at least partially quenched by destructive interference of the wave components at least in one propagation direction, wherein compression oscillations of the fluid can be excited by the respective total wave and the compression oscillations can be conducted through the fluid to a respective other one of said first and said second oscillation transducer and recorded there by said control device in order to determine measurement data, wherein the fluid quantity can be determined by said control device in dependence on the measurement data.
