Abstract
An ultrasonic measurement apparatus (10) for determining a fluid velocity of a fluid (12) flowing in a piping (14) is provided, the apparatus (10) having a measurement body (20) inserted into the piping (14) and thus forming a section of the piping (14), the measurement body (20) comprising a flow channel (26) for the fluid (12) and a surrounding channel wall (24), wherein at least one ultrasonic transducer (18a-b) is mounted from the outside on the channel wall (24) so that an oscillating member of the transducer (18a-b) couples onto a partial region (30a-b) of the channel wall (24) and thus the partial region (30a-b) acts as an oscillating membrane of the ultrasonic transducer (18a-b). The ultrasonic transducer (18a-b) is arranged within a bulge (44) of the channel wall (24) which protrudes into the flow channel (26).
