Does anybody have a program to calculate gas consumption using an analog gas meter? I have Racine gas meter on a site that was provided by the mechanical contractor and as per spec is an analog meter which sends a 4-20ma signal. I'd like to convert this reading as accurately as possibe to totalize the gas consumption. The meter is conencted to a Reliable Controls MachPro-Sys, so any style of BASIC can be modified to work. I've tried a couple of variations of code but I don't think I'm getting very accurate numbers. ANy help appreciated.
