In order to use industrially sonochemical processes, it is requested that large scale sonochemical reactors to be developed and designed. The impedance of the transducer and the sonochemical efficiency were strongly dependent on the liquid height. The maximum sonochemical efficiency was obtained for the minimum impedance of the transducer. On the other hand, the efficiency became minimum for the maximum impedance. From the above results, it is indicated that the impedance is one of important parameters to optimize sonochemical reactors. In this work, we measured the sonochemical efficiency by KI method using an automatic control system driven by the frequency which was controlled automatically in the way of keeping the impedance at the minimum level. The electric power was also controlled automatically. The frequency and the amplitude were controlled from a P.C. using GPIB and USB. Electric power, voltage and current were read into the P.C. in the same way. In the case of using the frequency control system, the sonochemical efficiency increased compared with that obtained at a fixed frequency. It was shown that the automatic frequency control system is very effective to optimize the sonochemical reactors.
