    So there seems to be some confusion at my plant over what the definition of a SLPM is. Some say it is a conversion to account for the fact that we are not measuring at STP, whereas others see it as converting the compressed liters into standard liters i.e. 5LPM @ 100psi = 38LPM @ 14.6psi. It...
