A very active1st day for this thread with a lot of interesting discussion
30 votes for definitions of SAC, 50% more than for RMV. I assume more respondents are familiar with the term SAC than RMV. Sixty percent voted that SAC was volume/min/atm, only 40% that it is pressure/time/atm.
20 votes for the definitions of RMV with 95% saying that it is volume/min/atm
This topic has been discussed many times with no consensus reached, this thread is no different. When communicating your gas consumption, give your units, cu ft/liters or psi/bar per minute per atm. Volume/min/atm is cylinder independent and valuable for gas planning, regardless of what you call it.
