  In this paper, we characterize the potential function $f$ of the almost
conformal gradient Ricci soliton on a Sasakian manifold in terms of the
non-dynamical scalar field $p$ and deduce the necessary condition for the
potential function $f$ to be constant. Furthermore, a relation between
$\lambda$ and the potential function $f$ has been established. Finally, we
prove a sufficient condition for an almost conformal Ricci soliton to be an
almost conformal gradient Ricci soliton and also a characterization of the
soliton in terms of shrinking, steady or expanding has been done.
