[0002] In the production process of non-ferrous metallurgy industry, electrolysis in hydrometallurgy is an important process technology. In the process of monitoring multiple parameters of the electrolytic cell, the anode liquid flow in the electrolytic cell is an important parameter, which must be real-time and accurate. At present, there is no special measuring device or means to realize the monitoring of this parameter, and only manual observation is used to adjust the liquid balance in the production process.
