This contribution will show how simultaneous group and phase velocity measurements can be used to calculate the sound velocity of the pure liquid, even if gas bubbles are interspersed. Apart from that it will be shown that for a given bubble size and operation frequency of an ultrasonic sensor only a certain volume fraction of gas is tolerable.
