远距离液面指示器即压差式低温指示器。它有很多优点:结构比较简单,制造容易;安装位置无限制,可安装在氨压缩机房内,观察方便;反应较快,工作稳定,指示的液面也比较准确,不需要电气设备,节约能源。因此,国内已有一些厂家将它安装在氨压缩机房内,用于观察氨液分离器,中间冷却器的液面。但是,笔者发现使用这种指示器的厂家只是少数,有的厂家虽已安装了这种指示器,由于安
Long-range liquid level indicator that differential pressure low temperature indicator. It has many advantages: the structure is relatively simple, easy to manufacture; installation position is unlimited, can be installed in the ammonia compressor room, easy observation; fast response, stable work, the liquid level is also more accurate, do not need electrical equipment, energy conservation . Therefore, some domestic manufacturers have it installed in the ammonia compressor room, used to observe ammonia separator, the level of the intercooler. However, I found that only a few manufacturers use this indicator, although some manufacturers have already installed this indicator, due to security
