Abstract
A measuring device, in particular a flow meter, has a measurement tube for receiving or conveying a fluid, first and second oscillation transducers on a side wall of the measurement tube, and a control device. An operating method has the control device drive the first oscillation transducer chronologically in succession for respective mode-selective excitation of a first and a second oscillation mode of a wave conducted in the side wall of the measurement tube. The second oscillation transducer is driven similarly for a second measurement direction. The excited waves are conducted directly in the side wall or indirectly through the fluid and recorded in the other oscillation transducer, resulting in measurement data for each measurement direction and oscillation mode. Result information relates to a property of the fluid or a state of the measuring device determined from the measurement data for both measurement directions and both respective oscillation modes.
