气泡管液位测量仪是一种独立仪器，用于精确显示液态熔硫罐中的液位。该系统成本低廉，可通过密度和压力测量液位。

它尤其适用于熔硫罐，我们就在这里相遇：
- 被硫磺粉污染的顶部空间，可在发射机内/上结晶。
- 泡沫环境会使发射机失明。
- 加工温度高。
- 法兰安装的变送器没有侧面连接。
- 不应与发射机直接接触的腐蚀性环境。

气泡管系统已经使用了几十年，其操作简单，加上电子仪器的最新技术，使这些系统成为熔硫池液位测量的首选方法。

所有气泡水平仪都由两部分组成：
• A dip pipe immersed in the liquid sulfur.
- 控制柜中装有压力调节器、流量计和压力指示器。

The Bubble Tube works by measuring the amount of pressure needed in order to release a constant airflow through the dip pipe submerged in the liquid sulfur. Thus, the system requires air supply at all times. The air enters the control cabinet, goes through the dip pipe, and leaves it from the bottom, producing air bubbles. Changes in the measured level cause the air pressure in the bubble tube to build up or drop. An integral pressure indicator measures the backpressure and transfers the signal to the DCS, which translates the pressure signal received into the level in the tank. This method allows for a clean level measurement as liquid sulfur will not enter and block piping or other parts of the instrument.
