We say that the flow S, is a Bernoulli flow of finite entropy if, for each fixed to, St0 is a Bernoulli shift of finite entropy. We proved the existence of Bernoulli flows in [2]. By a trivial normalization (change the time scale by multiplying all t by a fixed constant; that is, speeding up or slowing down the flow by a fixed constant) we can assume that E (S,)= 1. In this paper we will show that any two Bernoulli flows with the above normalization are isomorphic. We say S1 acting on X is isomorphic to S, acting on X if there is an invertible measure-preserving map y of X onto X and, for each fixed
