1、摘要随着计算机技术和现代通信技术的迅速发展，水位控制器已经从普通型发展到智能化，而且水位控制器的功能FI益趋向于完善。水位控制器是近年来开发的一项新技术，它是传感器、硬件、软件等几项技术紧密结合的产物，它的作用是观测和控制容器内的介质多少量，通过液面的高度来掌握体积的多少，从而达到防止超装和掌握存液数量的目的，可用于很多地方进行工业控制。木次设计主要针对锅炉进行口动检测、口动控制等多项功能，其主要任务是保证锅炉的安全、稳定、经济的运行，减轻工作人员的劳动强度，由于我国水位控制操作水平落后，工作人员过多，但是现在水位控制器为水位控制开辟
2、了广阔的前景。对水位控制器研究，有利于满足人们日益增长的物质需求，通过将科学技术应用到水位控制上从而使得人们真止体会到科技的发展给口己的现实生活所带来的方便和舒适。关键词：单片机水位控制器传感器A/D转换AbstractAlongwiththecomputertechnologyandModernCommunicationTechnology'srapidlyexpand,thewaterlevelsurveymeteralreadytosaidfromthepopulartypedevelopstheintellectualizat
