Hello:
With natural gas for home heating being so expensive now, was wondering a bit about the calibration of our gas meter.
a. How well do these things hold calibration ?
b. If they do "drift" some, is there a recognized tendency for them to show more or less usage ?
c. What's a good rule of thumb regarding how often to request the gas company to re-calibrate them ? Do they have to honor your request (by Law) ?
Thanks, Bob
