摘　　要：液位测量适用于生产生活的各个方面,是现代测量科学的重要方向。电容式液位测量较为常见,但是测量精度容易受外界环境干扰。为了提高液位测量的精度,提出了一种新型的高精度液位测量仪。该系统以CC2530为核心处理器,AD7147为液位采集器,将传统的触摸屏用法改造为分段式液位测量用法,并结合外围传感器电路的设计,由于AD7147的可编程性和对环境因素引起的电容变化的屏蔽功能,实现了对液位高精度测量。经试验表明该测量仪系统稳定、测量精度可达到毫米级别。Level measurement is suitable for the production of all aspects of life,which is the important direction of modern measurement science.In order to improve the precision of level measurement,the paper introduces a new type of high precision level gauge.The system uses AD717 as the core processor,uses the touch screen for level measurement usage,combines with peripheral circuit design of sensor and realizes the measurement of liquid level.The prototype test show that the measuring instrument system is stable and with high precision.
