化工电解槽液位测量难题/The difficulty of liquid level measurement in chemical electrolytic cells

在化工领域，电解槽是一种常见且关键的设备，被广泛应用于各类化学反应过程 。但在实际的生产过程中，化工电解槽的液位测量面临着诸多复杂且棘手的难题。一是电解液易结晶，附着在槽壁、电极及测量装置上，直接阻碍测量信号捕捉，导致数据不准；二是电解反应生成的氟化氢等腐蚀性气体，会侵蚀仪表金属部件，降低精度甚至损坏设备；三是电解过程产生的电信号与电磁场，会干扰测量仪表的信号传输，造成数据波动、失真，难以实现精准监测。

In the field of chemical engineering, electrolytic cells are common and crucial equipment, widely used in various chemical reaction processes. However, in the actual production process, the liquid level measurement of chemical electrolytic cells is confronted with numerous complex and intractable problems. First, the electrolyte is prone to crystallization, adhering to the cell wall, electrodes and measuring devices, directly hindering the capture of measurement signals and resulting in inaccurate data. Secondly, corrosive gases such as hydrogen fluoride generated by electrolytic reactions can erode the metal parts of the instrument, reduce accuracy and even damage the equipment. Thirdly, the electrical signals and electromagnetic fields generated during the electrolysis process can interfere with the signal transmission of measuring instruments, causing data fluctuations and distortions, and making it difficult to achieve precise monitoring.
