Automatic Flow Control for Therapeutic Ozonizer D. Lodos, A. Fuste, E. Limonta Ozone Research Center, Cuba. In ozone therapy it is fundamental the control of the ozone concentration applied to the patient according to the treatment. This parameter strongly depends on the oxygen flow that passes through the ozone generator. In this work a system for the automatic control of oxygen flow is developed. It assures the selection and stability of the gas flow and the switch off of the equipment in case of failure in the supply.
