Looking for a Gas Usage Monitor Sketch

[markk]

Hi. I've just started off with mysensors and am trying to work with my 13 year old daughter to teach each other a few things as well as create some interesting sensors. We've got the energy pulse meter working great but that's mainly because the sketch worked out of the box. our Gas meter monitor is causing some issues, however. We are using the pulse water meter sketch which we've tried to adapt without success. you see, as far as I can gather, our gas meter is an old Schlumberger and measures pulses at one per ft3 and we can't get the calculations correct. I'd also love to get the starting point the same as our current meter reading. we've been googling for days! Has anyone got any info to point us in the right direction please
