US300 Series

The measuring principle of transit-time ultrasonic flowmeters is based on the influence of the flowing fluid on the traveling time of the ultrasonic signal. The signals are transmitted through the pipe and the transit time difference between the forward and backward signals is used to determine the flow velocity.

The transducers are clamped on the outer pipe wall without touching the liquid. Thus, there is no risk of contamination and it is suitable for ultra clean liquids. There is also no risk of corrosion, which is suitable for aggressive liquids as well.

Yokogawa's transit-time ultrasonic flowmeter, with our advanced technologies, provides fast and accurate measurements in clean to dirty liquids, requiring no zero flow adjustment.
