Abstract

In the paper directivity characteristics of the wetted transducers in gas are discussed. Investigations show that the different width of the directivity pattern in the upstream and downstream direction of a measurement channel determines the different amplitudes of ultrasonic signals. In the downstream channel the amplitude of ultrasonic signal is large than in the upstream channel.
