摘要：
Method and corresponding device for determining a flow speed in a fluid conduit. The fluid conduit is provided with first, second and third ultrasonic transducers, wherein respective connection lines between transducers extend outside of a symmetry axis of the fluid conduit. First and second measuring signals are applied to the first ultrasonic transducer and received at the second and the third ultrasonic transducer, respectively. The measuring signals comprise a respective reversed signal portion with respect to time of a response signal. Respective first and second response signals are measured and the flow speed is derived from at least one of the first and second response signals.
