Tracking performance of an ozone system real-time is valuable for pilot test and even full-scale ozone systems and may be easier than you think.
Ozone system output is measured in g/hr or lb/day. These values indicate the production rate of an ozone system. Knowing the production rate of your ozone system real-time can have value in tracking system performance and preventing system failures by spotting potential issues before they start.
To calculate ozone production both the oxygen flow-rate and ozone concentration must be measured. Both of these values can be measured real-time with digital devices installed inline with your ozone system.
Mass Flow Meter:
The GFM Mass Flow Meter will measure and display oxygen flow through your system real-time with a pressure compensated flow rate. A mass flow meter measures the overall mass of gas passing through the device using ultrasonic technology. This ensures reliable and repeatable flow measurements that do not require any conversions for temperature or pressure changes to the gas stream. An LCD display or digital output can be provided to record oxygen flow rate.
UV Ozone Analyzer:
The UV-HCR Ozone Analyzer will measure ozone concentration real-time to indicate the actual concentration of ozone produced by your ozone generator. The UV Analyzer uses UV absorption technology to measure ozone concentration. This unit provides an LCD display or digital output to record ozone concentration.
A sidestream of ozone gas must flow through the UV ozone analyzer (1-2 LPM). Some of the ozone will be destroyed in the UV lamp measurement tube, the remaining must be converted back to oxygen safely using an ozone destruct device.
Oxygen Purity Meter:
The OXM-12L Oxygen Purity meter will measure oxygen purity real-time to ensure the oxygen purity remains stable and sufficient for efficient ozone production. Ultrasonic technology is used to measure the composition of gas and ensure oxygen purity remains consistent. This unit provides indicator lights to display oxygen purity and a digital output, an LCD display is optional.
Data from each of the devices can be input into a PLC for real-time calculation and reporting of ozone production in g/hr or lb/day. Data can also be recorded with a simple datalogger that can record data from each device real-time to be recorded for later review.
When measuring ozone concentration in % by weight the feed-gas (air or oxygen) must be factored into the calculation as oxygen and air have different weights. When calculating a percentage of a weight, it is necessary to know the weight of carrier gas.

Ozone generator output
((LPM x 60) x 0.001) x g/m3 = g/hr
Example = ((10 LPM x 60) x 0.001) x 10 g/m3 = 6 g/hr ozone production
Ozone Concentration in air by weight
100 g/m3 = 7.8% O3
1% = 12.8 g/m3 O3
1% = 7,284 ppm O3
Ozone Concentration in oxygen by volume
100 g/m3 = 6.99% O3
1% = 14.3 g/m3 O3
1% = 6,520 ppm O3
