Since December 2010 the CMD-3 detector has taken data at the electron-positron collider VEPP-2000. The collected data sample corresponds to an integrated luminosity of 60 1/pb in the c.m. energy range from 0.32 up to 2 GeV. Preise luminosity measurement is a key issue for many experiments whih study the hadronic cross sections at e+e− colliders. The integrated luminosity of the collider was measured using two well known QED processes e+e−→e+e−, γγ. The preliminary results of the luminosity measurement are presented in the various energy range. The current accuracy of the luminosity determination is estimated to be 1%. The study of the different systematics is in progress now and in forthcoming future we hope to reduce it to the level of ~0.5%.
