Abstract: With the development of microelectronics technology, increasingly intelligent and relevant national policies and support growing, its role in the measurement region has become more significant. In industrial production and daily life, it is often necessary for liquid level measurement, of which microelectronic technology is adopted as the control system, having advantages of miniaturization, low power consumption, and high reliability. Eddy current type displacement sensor is introduced in this paper, based on the single chip microcomputer electronic control system of liquid height measurement. This system uses single-chip microcomputer as the core control system, and controls liquid level data collection, management, and telecommunications. Small size, easy maintenance, high reliability, real time measurement and displaying the liquid height value, recording historical data remote transmission and so on are advantages of this system. This paper comprehensively applies knowledge in the areas of sensors, micro-controller, and introduces in detail the overall structure and control methods of electronic control system of liquid height measurement. This study implements the miniaturization and intelligentization of electronic control system of liquid level measurement, and based on contact measuring method ensures the measurement accuracy, which can reduce the complexity of measuring devices, save material, having important practical significance and significant social benefits.
