A maximum of 4 g/h of ozone is needed in a process.
The OZVb 1 A is available with its performance data:

Determining the gas flow rate:
If 10 g/h with the OZVb 1 A equates to 100%,
then 4 g/h equates precisely to 40% ozone output:
4 g/h * 100% / 10 g/h = 40%
1.
In the performance diagram for the OZVb 1 A - see above -
draw a horizontal line along from the required maximum
ozone output N - here 40% - until it intersects with the per‐
formance curve.
2.
Then draw a vertical line from this intersection point to the
axis F, “Gas flow rate”.
3.
Read off the value at the intersection point on axis F “Gas
flow rate” – 21% in our example. This then equates to a
multiplier of 0.21.
