Abstract

A flow ratio control system using is introduced. It is composed of Sensor, Flow meter and Mitsubishi PLC, which is the core of the control system, and some other equipment as an example that Potassium Chloride and Sulfuric acid make Potassium Sulfate to introduce this control system using in the chemical industry. This control system controls the flowing of the Sulfuric acid based on the flowing of Potassium Chloride, satisfying the demanded of the technological requirement. The result of practiced application indicates that this system has high control precision and good Stability.
