  • Ultrasonic measurement of flow velocity
    Patent number: 8291773
    Abstract: An ultrasonic measurement device (10) for determining a flow velocity of a fluid in a conduit comprises a pipe section (12) having a central longitudinal axis (22) and a cross section (24) with a radius (R), the central longitudinal axis (22) defining a horizontal reference plane (26); at least a first two-path measurement system with a first path (30a) and a second path (30b) defined by a first pair of ultrasonic transducers (32) and a second pair of ultrasonic transducers (32) mounted to the wall of the pipe section (12), the ultrasonic transducers (32) of each path (30a-b) opposing each other at the ends of their path (30a-b), each path (30a-b) oriented parallel to the horizontal reference plane (26) with a distance to the horizontal reference plane (26) while having a component transverse to the central longitudinal axis (22); first evaluation means (38) to determine a first flow velocity value from the first path (30a) by comparing the ultrasonic transit times along the first path (30a) with and again
