Abstract: 1 would like to first discuss with you Rockwells current capabilities regarding conversion to the metric system. As the United States and the gas industry gradually convert to the metric system, certain minor changes to domestic meters are necessary. We now have a hne of domestic meters that we call fully metric. We have for years provided a standard cubic foot domestic meter with a metric index where the conversion from the English system to the metric system was made in the gear ratio within the index itself. This gave a reading in metric units, but created some problems for the proving process. The output shaft of the meter represented cubic foot volumes, and lo prove the meter, the metric index had to be removed and a cubic fool index put on (he meter. This then allowed you to prove the meter on a prover with a cubic foot scale. This created some problems because certain public utility commissions do not allow you to prove the meter with an index other than the one that is actually going to be on that meter in the field.
