摘要
During sing-around-type measurement in a fluid, a transmitter (2; 3) repeatedly transmits sound pulses in the fluid, and these sound pulses are received by a receiver (3; 2), which acoustically is disposed opposite to the transmitter. The detection of the reception of a sound pulse at the receiver triggers the transmission of a subsequent sound pulse by the transmitter. In order to avoid any interference from multiple-reflected sound pulses, a delay (20) is produced with the aid of the frequency of the received sound pulse, and the transmission of the subsequent sound pulse by the transmitter is triggered with this delay.
