Beschreibung
Zusammenfassung:	The invention relates to a method (30) of and an apparatus (1) for determining a flow rate of a fluid and detecting gas bubbles or particles in the fluid. In order to provide a method (30) and an apparatus (1), which can be used to perform more precise measurements and to provide a better safety, the invention provides that a collapse of an amplitude of an ultrasonic signal is used for detecting gas bubbles or particles.
