Patent ID: 11231306

Abstract:
An ultrasound flow measurement apparatus (10) for determining the flow rate of a fluid flowing in a line (12) is provided having at least one measurement path (18) at which a first ultrasonic transducer (16a) and a second ultrasonic transducer (16b) are arranged opposite one another with the flowing fluid between them, and having an evaluation unit that is configured to calculate the flow rate from a time of flight difference of ultrasonic pulses along the measurement path (18) in the direction with the flow (14) and against the flow (14). The ultrasonic transducers (16a-b) here are positioned such that a specific part pulse is isolated in time in a received signal of the respective receiving ultrasonic transducer (16a-b), with the part pulse corresponding to a direct sound, a reflected sound, an axially broken fluid sound, or an azimuthally broken fluid sound.
