Hi
I need to know the mass flow rate of air passing through a chamber which houses an NDIR sensor, so I can relate that to the quantity of a particular gas passing through.
I was just wondering whether using an automobile MAF sensor (hot wire) would be wise. If it could be used, it would be very cost effective. Thing is, I am not sure how difficult it would be to calibrate. Is the output directly proportional, or does it follow some kind of map? And if so, is the map stored on the sensor itself or the car's ECU?
If anyone can help that would be great. Electronics aren't my forte
Thanks
