Question Water Level Monitor

Fuzzy is on a distinguished road

I am currently working on a simple capillary rise simulation (using transient model) for a cylindrical tube of 1 mm diameter. I got the simulation to run which shows the water level rising. But right now I'm trying to figure out how to extract a curve from fluent that might show the water level (y-axis) in relation to the time (x-axis). Does anyone have a suggestion on how to do it?

vinerm will become famous soon enough
There are at least two ways to do this, but the following one is good enough.

Create an iso-surface of water volume fraction 0.5. Essentially, this is the free surface. Report its average y-coordinate.
