Absolute neutrino cross section measurements are presently limited by uncertainties on neutrino fluxes. In this paper, we propose a technique that is based on the reconstruction of large angle positrons in the decay tunnel to identify three-body semileptonic K+ decays. This tagging facility operated in positron counting mode (“single tag mode”) can be employed to determine the absolute nu_e flux at the neutrino detector with O(1%) precision. Facilities operated in “event by event tag mode” i.e. tagged neutrino beams that exploit the time coincidence of the positron at source and the electronic neutrino interaction at the detector, are also discussed.
