Can a CO2 Flow Meter Measure a CO2/N2 Mixture?

We recently purchased a CO2 flow meter (SKU: ATO-FLOW-MF5700) for our setup, and I’m trying to understand whether it can be used beyond pure CO2applications.
In our case, the gas stream is actually a mixture of CO2 and N2, and the system operates under vacuum conditions. Has anyone here tried using a CO2-calibrated flow meter in a mixed gas scenario like this?
Any insights would be appreciated.

You cannot use this CO2 flow meter to measure the flow of a CO2-N2 mixture directly; you need to tell us the percentages of CO2 and N2 in the mixture.

Thanks for pointing that out. Based on our current estimates, the mixture is roughly 90% CO2, 9% N2, and about 1% H2O. With that composition, would the flow meter still be usable, or would the readings be significantly off?

Yes, it will work.
So for your order, we will factory calibrate it according to these three gas percentages 90% CO2, 9% N2 and 1% H2O, instead of just calibrating it for CO2 gas, right?

That makes sense, and that’s actually where our concern comes in — we don’t have a fixed or well-defined gas composition at this point. In many cases, we’re working with nearly pure CO2 anyway. Would it be reasonable for us to proceed with standard CO2 calibration for now and only consider mixed gas calibration later if needed? Also, is field calibration something we could realistically handle ourselves?

When you want to apply it to a mixed gas, contact us and inform us of the relevant percentage of the mixed gas.
