I have to build a CO2 flow controller. We have a borrowed unit that uses 3-15 regulated CO2 through an I-P Controller to a Badger Meter valve.
This existing system comes right off the Cryogenic tank so it will see pretty cold gas when flow gets high.
I need to create this system with new parts and add a flowmeter.
Flows are calculated to be 0-100 SCFM but mostly around the bottom half of that. Pressure is under 100psi
Anyone done this and can steer me toward device choices? The existing unit works so I could just duplicate those parts but what gas flow meter would you recommend? And what about those combination flowmeter/ controllers like Brooks Mass/Flow ?
The cryogenic temp is what I puts me in unfamiliar territory. there are evaporators in front of this to flash it to a gas but stuff sometimes happens and I would not want liquid CO2 droplets to destroy an expensive flowmeter.
I appreciate any input you are willing to share.
