An $\text{AF}$ flow is a one-parameter automorphism group of an $\text{AF}$ ${{C}^{*}}$ -algebra $A$ such that there exists an increasing sequence of invariant finite dimensional sub- ${{C}^{*}}$ -algebras whose union is dense in $A$ . In this paper, a classification of ${{C}^{*}}$ -dynamical systems of this form up to equivariant isomorphism is presented. Two pictures of the actions are given, one in terms of a modified Bratteli diagram/pathspace construction, and one in terms of a modified ${{K}_{0}}$ functor.
