Abstract
To solve the problem of the electrode especially vulnerable to electrolytic corrosion in corrosive liquid level measurement, the detection of ultrasonic technology is applied to the industrial production level or materials. Carries out AT89S52 MCU as the core, establishes ultrasonic measurement of relationship between distance and speed and the transmission time, the method of detecting the height of the liquid level is realized by hardware circuit design and software programming, the ultrasonic ranging in the test of 20cm and 80cm two kinds of distance. The ultrasonic influenced by temperature, measure the temperature by temperature sensor, according to the temperature compensation formula, and the design of alarm module, when the temperature is too high. The results show that, the relative error of ultrasonic distance measurement was 2.5%and 1.25% respectively, the accuracy can meet the actual demand, to achieve the expected goal. The system has the characteristics of accurate measurement, low power consumption, long service life, can meet the general needs of industry.关键词
