| Abstract: | The ultrasonic power meter constructed by a cone-type float tethered three chains is developed. In the measuring range 0.5-22W, the sensitivity constant is 6.61mm/W and the erros of repeatability is better than 13.4%. The meter can be used for measuring the mean output sound power of various ultrasonic treatment instruments. |
