Fair - looks like we need to reveiw the search function again. 

Very simply, in 2d create an isosurface of VOF at around 0.5   That'll give you a line. Plot the vertical position on the line.

In 3d create the isosurface to visualise the water free surface.  Then create an isosurface of mesh that cuts the free surface whilst the free surface is selected. That will result in a "surface" that's actually a line of where the water level is on that vertical surface. 

If you need the value at a position, create a vertical line and then a clip surface of that line based on VOF of (for example) 0.5   Plot the maximum (or minimum) of position on the clip line.
