ABSTRACT:
An ultrasonic flow-measuring method measures 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. At least one correction parameter is established on the basis of the calculated sound propagation of the ultrasonic pulses traveling from one ultrasound transducer to the other, the calculation of the sound propagation of those pulses 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.
