| Abstract: | This paper describes a new control way, using volumetric flowmeter for flow signal detection. The flow signal is transmitted to the PLC analog module, to, thus the amount of sulfuric acid is regulated by the electronic precision small e- lectric regulating valve through the PID adjusting output, and the accurate control of sulfuric acid is realize. |
