METHOD OF MONITORING OZONISER OUTPUT AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2014 - IPC C01B13/11 

FIELD: chemistry.

SUBSTANCE: product consumption used is ozone concentration and the signal used is the amount of electric charge in an ozone-ion air mixture, which is measured over a period of time set by a control unit. The signal is then transmitted to a differentiating section which determines the rate of change of charge in cycles and generates a digital or analogue signal in form of electric voltage. The signals arriving at a counter in cycles are summed and the ozoniser is turned off if the resultant signal reaches a given voltage value. The apparatus includes an ozone output sensor 7 installed in front the output of the ozoniser 4, and has a coulometer 9 connected to the differentiating section 5 and the control unit, which consists of series-connected signal counter 10, signal amplifier 11 and a device for controlling the cyclic process of measuring the rate of change of charge 12. The output of the signal amplifier 11 is connected to a voltage controller 6. The sensor is in form of a thin metal plate, and the high-voltage electrode of the ozoniser is in form of a flat coil.

EFFECT: monitoring output of ozonisers.
