The VEPP-4M electron-positron collider is now operating with the KEDR detector for the high-energy physics experiments in the energy range from 1100 to 4000 MeV. For these experiments, monitoring of beam transverse position and angles at the interaction point is important for energy stabilization. BPM system of VEPP-4M doesn't provide the reliable information about beam orbit when the machine operates in colliding mode. The beam diagnostic instrument, described in this paper, is a good supplement for the BPM system. The vertical coordinate and angle of the beam can be measured and stabilized at two points, which are symmetrical with respect to the beam interaction point. The precision of the measurements and the collider energy range accessible for the diagnostics are discussed.
