摘要：
It is an object of the invention to provide a method and a device formonitoring the integrity of a flow circuit using a pressure measurement. Thedevicecomprises an input for a pressure signal, the pressure signal being indicativeof fluidpressure in a receptacle, and a signal processor configured to process thepressuresignal for detection of a beating signal formed by interference betweenpressurewaves generated by a pulse generator associated with the receptacle andpressurewaves generated by a pumping device (3). The signal processor (29) determinesthe integrity based on the presence or absence of the beating signal.
