ABSTRACT:
An ultrasonic flow-measuring method determines the flow rate of a medium flowing through a line is determined by measuring the runtime of an ultrasonic signal that travels from a first ultrasonic transducer to at least one other ultrasonic transducer. The runtime of the ultrasonic signal as it makes m passes in immediate succession through a predefined path over a predefined path length and at a predefined angle relative to the flow direction is measured, and the runtime of the ultrasonic signal as it makes n passes in immediate succession through the predefined path over the predefined path length at the predefined angle relative to the flow direction is measured, with m and n being mutually different integers, and the dead time of the ultrasonic flow-measuring process is determined on the basis of the measured runtimes. This ultrasonic flow-measuring method permits real-time compensation for the dead time during the actual measuring process, the result being highly accurate measurements.
