An ozone concentration sensor for use with an ozone generator. The ozone free feed gas to the ozone generator is briefly fed to the sensor which measures both the temperature of the feed gas and the time it takes a high frequency sound pulse to travel a predetermined distance in the feed gas for reference date. A portion of the output gas from the ozone generator is then fed to the sensor and the same measurements are made for the output gas. A programmed microcomputer determines the ozone concentration in the output gas from the measurements. In one embodiment, the sensor constantly receives output gas from the ozone generator. The reference measurements are made while operation of the ozone generator is briefly interrupted and feed gas passes through the ozone generator unchanged. Reference measurements may be stored and used for repeated ozone concentration calculations, so long as there is no significant change in the feed gas.
