Zusammenfassung:	The invention relates to a gas bubble sensing device (1) with two ultrasonic transducers (2, 3, 8, 9). In order to be able to detect gas bubbles with different sizes reliably, at least one of the ultrasonic transducers (2, 3) comprises a plurality of segments (2', 3') that can be operated independent of each other.
