Abbreviations  For these formulas
GPM  Gallons per Minute
PPM  Parts per Million
g/hr. Grams per Hour
SLPM  Standard Liters Per Minute
% O3 Percentage Ozone concentration
 g/m3 Grams per Cubic Meter
CFM  Cubic Feet per Minute

 Flow Rate and Desired PPM Conversion in Water
Use this calculation to determine the necessary ozone production to achieve a specific ozone dosage into a water flow. 
GPMPPMg/hr.
(3.78 • 60 • GPM • PPM) / 1000 = g/hr.

 Output of an Ozone Generator using Oxygen Feed-gas
Use this calculation to determine the output of an ozone generator on oxygen feed gas. Enter the standardized flow 
rate of oxygen and the concentration
of ozone to determine the production of your ozone generator. This calculation
only works with oxygen feed gas.
SLPM % O3 g/hr.
%
SLPM • 0.001 • 60 • 14.3 • %O3 = g/hr.

 Output of an Ozone Generator using Dry Air Feed-gas
Use this calculation to determine the output of an ozone generator on dry air feed gas. Enter the standardized flow 
rate and the concentration of ozone in this dry air to easily determine the production of your ozone generator! This
calculation only works with dry air feed gas. 
SLPM% O3g/hr.
%

SLPM • 0.001 • 60 • 12.8 • %O3 = g/hr.

 Output of an Ozone Generator from g/m3 of Ozone
Use this calculation to determine the output of an ozone generator when you know the flow rate and ozone 
concentration in grams of ozone per m3 of air/oxygen. This calculation removes the question of what type
of feed gas is being used and can be used with either dry air or oxygen
SLPM g/m3 g/hr.
SLPM • 60 • 0.001 • g/m3 = g/hr.

 Output of an Ozone Generator from PPM of Ozone & Flow Rate
Use this calculation to determine the output of a commercial ozone generator. If you do not know the flow 
rate, it can be measured with a wind speed meter and calculated. Using the airflow rate in CFM and the
ozone level in PPM, the output of the ozone generator in milligrams/hour can be determined. This calculation
can also be used to determine the amount of ozone necessary to treat a flue gas stream or many other
industrial emission control applications. 
CFM PPM mg/hr.
CFM / 35.33569 • 60 • PPM • 2.14 = mg/hr.

 Adjusted Flow for Pressurized Flow Meters
PSI Measured Flow Actual Flow
