Good morning all,
I'm looking for a good quality, high-ish resolution gas meter clocking chart PDF or image that I can reproduce and print cleanly to hand out to my students. Everything I see with a quick search online is too small and cruddy looking. Any help is appreciated.
Best to all,

Have you tried contacting PSE&G?

I still believe the best thing to do is teach them to memorize the math, then they'll always have it with them (in their head).
3600/seconds to pass 1 Cu Ft=CFH. now multiply that by the current BTU content of 1 Cu Ft.
if medium pressure gas through the gas meter ( 2 PSI in our area) 3600/seconds to pass 1 CuFt x 1.12= CFH.

I don't get it. So, if a 2 foot dial takes 34 seconds to make one full rotation, how do you apply your math?

It's actually a shame no one makes a phone app to do this.

After you make that expensive repair and you still have the same problem, What will you check next?

There's the PDF! Nice link, Ed! I put that math into a google spreadsheet but it's been a few years and I don't remember the math either just like ch4man said

Here is a spread sheet I just made up for that calculation.

Now you can google Clock Gas Meter Chart and maybe this will show up.

2 CF dial / 34 sec. x 3600 = total 211.76. CF

use 7200 instead of 3600. there are 3600 seconds in one hour, so there has to be 7200 seconds in two hours. in your example one could substitute 17 seconds instead and still keep the 3600 in the formula.

this entire trade requires math, at all levels. sure we can't remember everything so cheat sheets are nice but this one I found easy to remember

thanks Ed, I spout off 1.12 when doing a conversion for 2PSI gas but that reflects the local elevation above sea level where I'm at. one would need to adjust the math for their one location. or carry many cheatsheets............

Here's an actual calculator that will adjust for elevation. Check it out and let me know if it works.
I added it my other Excel SS of calculations if you want the whole shebang.

There was an error rendering this rich post.

See attached files. I wrote these for my guys. The worksheet correction factor is based on my local pressures.
Never stop learning.
