Beschreibung
Zusammenfassung:	A method for characterizing the gas load of a medium, which comprises a liquid loaded with gas, using a measurement sensor that guides the medium in at least one vibrating measurement tube, includes: determining a speed of sound value and a resonator density value of the medium based on natural frequencies of at least two different vibration modes of the measurement tube; determining a measured pressure value for the medium guided in the measurement tube; determining a gas volume content of suspended bubbles in the medium based on the resonator density value, the speed of sound value and the measured pressure value; and determining a value for the gas volume content of free bubbles based on the resonator density value of the medium and the gas volume content of suspended bubbles.
