The Fischer, Krieger, and fiber product covers of sofic beta-shifts are constructed and used to show that every strictly sofic beta-shift is 2-sofic. Flow invariants based on the covers are computed, and shown to depend only on a single integer that can easily be determined from the β-expansion of 1. It is shown that any beta-shift is flow equivalent to a beta-shift given by some 1 < β < 2, and concrete constructions lead to further reductions of the flow classification problem. For each sofic beta-shift, there is an action of Z/2Z on the edge shift given by the fiber product, and it is shown precisely when there exists a flow equivalence respecting these Z/2Z-actions. This opens a connection to ongoing efforts to classify general irreducible 2-sofic shifts via flow equivalences of reducible shifts of finite type (SFTs) equipped with Z/2Z-actions.
