GIWU-226 Series Ultrasonic Flow Meter
This Ultrasonic Flow meter adopts the time-difference measurement principle. The ultrasonic waves emitted by the sensor in a fluid, the flowing in the propagation direction of acoustic wave propagation velocity downstream increases, decreases the upstream direction, have different propagation distance in the same transmission time, measure the flow rate according to the difference of the transmission time and the fluid flow velocity. When the ultrasonic signal is transmitted through the flowing liquid, there will be a difference between the upstream and downstream transit time ( travel time or time of flight ), which is propor tional to flow velocity, according to the formula below.
