  Recent experiments have demonstrated the possibility of inducing
superconducting pairing into counterpropagating fractional quantum Hall edge
modes. This paves the way for the realization of localized parafermionic modes,
non-Abelian anyons that share fractional charges in a nonlocal way. We show
that, for a pair of isolated parafermions, this joint degree of freedom can be
read by conductance measurements across standard metallic electrodes. We
propose two complementary setups. We investigate first the transport through a
grounded superconductor hosting two interacting parafermions. In the low-energy
limit, its conductance peaks reveal their shared fractional charge yielding a
three-state telegraph noise for weak quasiparticle poisoning. We then examine
the two-terminal electron conductance of a blockaded fractional topological
superconductor, which displays a characteristic $e/3$ periodicity of its
zero-bias peaks in the deep topological regime, thus signalling the presence of
parafermionic modes.
