Abstract: Domestic meters can be defined as positive displacement meters having a capacity of 500 cubic feet per hour or less, operating at a differential pressure of Vz water column. These meters are generally classified by capacity and case material. Case materials used are tin plated steel, cast iron, and aluminum. In the Southwestern area in particular, and more and more throughout the United States, aluminumcase meters are becoming more popular. For this reason, and) the fact that the working principles are similar, this paper will be confined to a discussion of aluminum case meters. Domestic aluminumcase meters are manufactured in sizes AL-175, 5B-225, AL-250 and AL-425. The numerical portions of these designations denote the capacity in cubic feet per hour of 0.64 gravity gas while absorbing an average of xk water column pressure. The basic design for these meters was conceived by Glover in England in the early 1800s, and modern day domestic me- Figure 1.

Most positive meters are of a type described as having 2 diaphragms, 4 compartments, and using D slide valves.
