What causes the frequent fluctuations in the liquid level gauge of the lower column in air separation?

There are many reasons for fluctuations in the liquid level in the lower tower; these generally include whether the valve controlling the liquid flow operates properly, whether the operating conditions of the lower tower are normal, and whether the liquid level indication is accurate

Just line them up, and there should be no issues with the operating conditions; the valves are also fine

First, check whether there is any air leakage in the pressure lead pipe~~ Then, check whether the positive-pressure pipe (for the liquid) of the level gauge and its electric heater are working properly ~~

Check whether the pressure lead and pressure transmitter are functioning properly. It is possible for liquid to get trapped inside the pressure lead
