Method for measuring in a fluid with the aid of sing-around technique
(English)Patent (Other (popular science, discussion, etc.))
Abstract [en]

Sammandrag från US5796009 During sing-around-type measurement in a fluid, a transmitter repeatedly transmits sound pulses in the fluid, and these sound pulses are received by a receiver, 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 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.
