| 摘要 |
The invention relates to an ultrasound flow sensor provided with a transducer array for recording the flow rate of a flowing medium (2) in a duct (1, 3). Acoustic signals (24) are transversally injected in a flowing direction (30) of the flowing medium (2). An ultrasound transducer array (20) is associated with the wall (4) of the duct (1, 3) and comprises an transmitting part (21) for an emitted signal (24) and a receiving part (22) for reflected acoustic signals (25, 26). |
