It sounds like what you really want is the B.n line integral, which 
gives you all of the flux passing through a surface. This works "right" 
in the axisymmetric case, giving you the flux that passes through a 
cylindrical shell defined by the revolution of the prescribed contour 
about the r=0 axis.
