Abstract
A measuring device for determining a fluid variable relating to a fluid or fluid flow includes a control device, a measuring tube receiving the fluid or fluid flow, and oscillation transducers spaced apart on the measuring tube. At least one oscillation transducer is drivable by the control device to excite a wave conducted through at least one side wall of the measuring tube, the conducted wave exciting compression oscillations of the fluid conducted through the fluid to the other oscillation transducer and recorded there by the control device to determine measurement data. The fluid variable can be determined by the control device as a function of the measurement data. At least one further side wall of the measuring tube has at least one recess extending in a flow direction and increasing a flow cross section of the measuring tube. A method for determining a fluid variable is also provided.
