我局正在运行的热水锅炉和蒸汽锅炉的膨涨水箱、贮水箱的水位测量一直采用大连生产的水位深度指示仪。由于安装、使用及产品质量等问题,经常出现设备故障,致使发生缺水跑水现象,影响了锅炉的正常运行,不仅造成经济损失而且污染环境。为解决这一问题,即保证安全运行,又使用准确可靠,我们研制成功了这一水位自动显示装置。(见图1)它利用水做为导体,将220V电压通过100VA变压器转变为24V直接输入水中的各个位置,通过 Our bureau is running hot water boiler and steam boiler expansion tank, water tank water level measurement has been used in Dalian produced water level indicator. Due to installation, use and product quality problems, equipment failure often occurs, resulting in running water shortage phenomenon, affecting the normal operation of the boiler, not only cause economic losses but also pollute the environment. To solve this problem, that is, to ensure the safe operation, and the use of accurate and reliable, we developed the water level automatic display device. (See Figure 1) It uses water as a conductor, the 220V voltage through the 100VA transformer into a 24V direct input into the water in various locations, through
