| Abstract: | The manufacture and experimental results of the transducer system for the acoustic communication meter have been introduced in this paper. A wider frequency response has been obtained by using the coupled principle of the liquid cavity vibration and the radial vibration of the free flooded transducer, and a higher directivity has been formed at the vertical direction of the transducer by using the acoustic reflection system so that the directivity index of the transducer can be increased by 22 dB. |
