An ultrasound flow measurement apparatus () for determining the flow rate of a fluid flowing in a line () is provided having at least one measurement path () at which a first ultrasonic transducer () and a second ultrasonic transducer () 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 () in the direction with the flow () and against the flow (). The ultrasonic transducers (-) here are positioned such that a specific part pulse is isolated in time in a received signal of the respective receiving ultrasonic transducer (-), with the part pulse corresponding to a direct sound, a reflected sound, an axially broken fluid sound, or an azimuthally broken fluid sound.

Ultrasound flow measurement apparatus and method for determining the flow rate

An ultrasound measuring apparatus for measuring the flow rate of a fluid in a conduit having two measurement systems is provided that each have at least one pair of ultrasound transducers that span a measurement path between them and that each have a control unit to determine transit times from ultrasound transmitted and received with and against the flow. In this respect, the control units are each configured to fix measurement times for a transit time determination on a measurement path autonomously and independently of one another in accordance with a rule that produces a respective different sequence of the measurement times in both measurement systems.
