Hello all,
Working on a small project, and the hardware guy ducked out on us, so I'm picking up some of that slack to keep rolling. Wouldn't mind some suggestions from those with experience in this area.
-2 mass flow controllers for nitrogen and butane gases, from 16 psi regulated sources at normal room temperatures, no special ratings really necessary
-Low volume flow into canisters which are open to atmosphere (approximately tens of grams/hour, varies a bit by canister size)
-RS232 or analog input control preferred, but not tied to it, and we haven't bought any control hardware yet
-Device display isn't necessary, wouldn't turn it down though
-Call it a small industrial project. Have some budget, can't throw money at it like crazy though.
-Internal PID control is nice, precalibrated for our gases looks like a nice bonus too.
Our first lead was the various Sierra SmarTrak series, looks like both MKS and Alicat have roughly similar offerings. Any raging success stories with any of those? Deep undying hatred? Other manufacturers I should consider as I drop down the rabbit hole of spec sheets?
Thanks,
Mark
