The ultrasonic inline flowmeters measure a wide range of electrically conductive and non-conductive liquids independent of viscosity, temperature, pressure, or density. Ultrasonic waves can be used to reliably measure the volume flow of a wide range of homogeneous liquids.

Ultrasonic flowmeters operate on the principle of measuring the transit time difference of ultrasonic waves traveling in and against the direction of flow of the liquid. (velocity measurement by means of transit time difference) Velosity measurement is based on the measuring of the transit time of ultrasonic signals between two sensors (upstream and downstream). The signal transit time td in flow direction is shorter than the signal transit time against the flow direction tu. The difference between these two transit times is proportional to the average flow velocity along the measurement path.
