红外开关式智能液位监测系统

An Intelligent System with Infrared Switch for Liquid level Monitoring

设计了一种红外开关式液位监测系统，该系统结构简单，无任何可动部件，测量部分与待测液体介质完全不接触，造价低廉，通用性强，可与一些老系统（装置） 兼容，能远距离传输信号，实现中央控制室集中监控，具有可靠性高、寿命长、使用方便等优点．

A system for liquid level monitoring is designed. The structure of the system is very simple. All the components of the system are stationary and not in contact with the liquid. The cost of the system is lower. The signal detected by the measuring circuit of the system can be transmitted to a remote central control room. It is of high reliability, long life and easy to be operated. It is also with good gluerality and is compatible with some old systems or devices.
