ULG1000 系列 玻璃管式液位计（双色）Glass-tube Level Indicator (double color)

基本原理：

根据光的反射，折射原理而设计。有液体时，光的折射率将发生变化。可在观察窗看到液绿气红的彩色显示，从而读出液位。

性能特点：

红，绿双色显示

结构简单，安装方便

用途: 适用于石油化工等行业的各种贮罐，特别适用于温度压力较高且较清洁液体的液位显示。

材料： 碳钢，石英玻璃，不锈钢

工作温度： 介质：-50 -450℃

工作压力： 最大6.3MPa 

输出方式: 双色直观显示

安装方式： 容器侧面安装：平法兰：HG20583 DN20 ，凸法兰：HG20595 DN20 

It is based on light reflection and refraction principle. It can be observed by observation windows. Green color displays liquid and red color displays gas which can be seen by observation windows.
