How to determine dual levels in a glass plate level gauge?

“What does “double liquid level” mean? Please explain clearly. Does that mean there are two liquid levels: a liquid level and a interface level? Because their densities are different.
A level gauge composed of two or more glass plates. The liquid level is indicated on both level gauges
This indicates that the connection line of a glass plate level gauge is blocked. Try to check by turning it off to see which one has a blockage issue.

Both level gauges are working properly and not clogged
A glass plate level gauge operates on the principle of a communicating vessel; there should be no problems as long as it isn’t blocked. Check to see if there is any blockage, or if a self-sealing steel ball inside the level gauge is blocking the flow path. In principle, when the level gauge is installed at an appropriate position, the issue you mentioned shouldn’t occur.
