Abstract:
1. An ultrasonic flow-measuring method serving to measure the flow rate of a medium traveling through a measuring conduit, by means of two ultrasound transducers which in the flow direction of the medium are offset relative to each other and both of which alternate in emitting ultrasonic pulses while the respective other ultrasound transducer receives the emitted ultrasonic pulses and the flow rate is determined as a function of the run times of the ultrasonic pulses received by the respective other, ultrasound transducer, wherein, on the basis of the calculated sound propagation of the ultrasonic pulses traveling from one ultrasound transducer to the other, at least one correction parameter is established, the calculation of the sound propagation of the ultrasonic pulses traveling from one ultrasound transducer to the other is made by taking into account a predefined frequency spectrum of the oscillations of the ultrasound transducers, and the flow rate is calculated by applying the correction parameter established.
