【正文】 riodically clean the ultrasonic probe. This design uses the configuration king with magic flap bined with the acid tank level control simulation. Monitoring interface design with Configuration, acid tank level control as a process control, production of a level monitoring system design. The use of established engineering, equipment variable definitions, screen drawing, animations, links, and mand language for the preparation, pletion KingView software design. There reaction graph screen, the historical curve, realtime curve, the alarm screen, report screens, each able to achieve the flexibility to switch between, so the screen can achieve animation effects or data or curves show. System can realize data input, dynamic data display and realtime monitoring of field devices, missioning and operation. The system processes visual display, friendly interface, easy to operate. The system is stable, low maintenance costs, for engineering applications related to a certain value. Keywords: KingView, measurement accuracy, acid tank level control.
