    Analog Gas Meter

    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.

    Most gas meters (utility) are pulse signals. You need to find the cut sheet on the Racine meter to determine how the signal corresponds to realtime gas consumption. I suppose 20mA could be full gas flow and 4mA would be 0 flow??? If this is the case, you will need a tight sample rate (no greater than 1 second to properly record consumption).
