Abstract:

The paper introduces the design idea of oilwater interface monitoring system which has two operating modes based on capacitive sensors,expounds the working principle of the sensor and the monitoring principle of system;When the system works alone,the MCU processes data and shows the position of oilwater interface,controls the equipment turn on the water automatically and to display of liquid level dynamicallyThe serial communication connection is designed in order to carry on the system expansion and realize the concentrate control by PC.

Key words: water surface;capacitive sensors;serial communication;monitoring
