FUNDAMENTALS OF MULTIPATH ULTRASONIC FLOW METERS FOR GAS ...
Flow the transit time is equal in both directions and the measured time of flight difference them (T ab T ba) is zero. Thus with flow the transit time of the signal traveling with the flow will be less than that of the signal traveling against the flow due to the velocity of gas within the meter body (Figure 4). tAB tBA L V cos c v L tAB cos BA ...

Transit Time Flow Meters - Kele
Flow. Since sound energy in a moving liquid is carried faster when it travels in the direction of fluid flow (downstream) than it does when it travels against fluid flow (upstream), a differential in the times of flight will occur. The sound’s time-of-flight is accurately measured in both directions and the difference in time-of-flight ... Doc Viewer
