Abstract: The definition of an acceptable internal leak in the 19th century obtained from a regulation published in England in 1859, titled An Act of Regulating Measures Used in Sales of Gas: A meter shall be tested for soundness or leakage with gas under pressure equal to a column of water three inches high, with a light or lights consuming not more than one twentieth part of its measuring capacity per hour marked thereon. The specifications have not changed much over the past 114 years. A recognized specification requires W CFH 5% as an acceptable internal leak. If a meter has an internal leak of % CFH. assuming 200,000 cubic feet of gas are consumed by a customer, the error would be 1% of the gas not registered. The standard present method of determining an internal leak requires the meter to rotate one revolution over a prescribed period of time.
