With the rapid development of the national economy,in the production,many industries will require the logic control of liquid-level.Logic control is good or bad,not only has the great impacts for stability operation and safety of equipment,but also has the significant role for production efficiency and cost control.Based on the working functions of fiber liquid-level sensor,combined with the actual production liquid-level control applications in the study,it is described that how to directly use fiber liquid-level controller to realize liquid-level control logic to reduce cost and failure rate...
