Abstract: The ozonization installation comprises a group of n ozonizers supplied with energy by a common source in a successive alternating voltage wave train mode, the application of the wave trains being controlled by a control device. The latter produces initiating signals which selectively enable the passage of the electric energy in the form of wave trains coming from the common source to the ozonizer. The installation comprises a servo system chain comprising devices for controlling the duration of the initiating signals by means of a set signal, having regard to the total ozonization produced by the n ozonizers. This duration corresponds to that of each successive wave train. Synchronization devices are provided for connecting the common energy source to solely one ozonizer at a time.

Abstract: This device for measuring a physical operating characteristic of an ozonizer such as, for example, the ozonization power, the production of ozone or the concentration of ozone in the air, comprises a medium or high-frequency sensor placed in the ozonization zone of the ozonizer and an electronic processing circuit which delivers a signal which is an image of the energy received by the sensor. The sensor detects the medium or high-frequency energy produced in the ozonizer and produces a signal which is an image of one of the aforementioned physical characteristics owing to the fact that the curves of these characteristics are colinear with those of the medium and high-frequency energy components.
