Abstract

This contribution presents a measuring system and in particular the signal processing for the simultaneous measurement of the flow velocity and direction of air and water in a partially filled pipe. The measuring system utilizes the ultrasonic time-of-flight principle to measure the flow velocity of each medium. Test measurements in which the ultrasonic transducers were moved by a linear axis through static media showed that small flow velocities of less than 1 cm/s can be clearly distinguished from 0 cm/s in water as well as in air.
