Development of Ultrasonic Copper Washing Tower Level Meter WANG Yin-guan, ZHONG Wei-dong, YAO Guo-min, SHEN Shu-rong, LI Zhi-liang (Institute of Acoustics, Tongji University, Shanghai 200092, China) 1 INTRODUCTION The level of stable copper washing tower is an important control index for copper washing. When the liquid level is too high, the gas will entrain the copper liquid, resulting in the loss, which will cause the copper liquid to be brought into the synthesis tower in severe cases, poisoning the synthesis catalyst and affecting the production.
