Abstract: main parts: the body, front, back, top, index box, and nandhole disc. The body (including table, partition, outlet channel and diaphragm channels) is cast in one piece. The body and top are molded from fine gray iron. The front and back are of the same material, with the exception of the SB, lOB, 20B, and 25B low pressure designs, in which pressed steel is used for front and back. The inside of the case is -horoughly cleaned and treated with a protective coating which prevents corrosion from water vapor and sulphur gases. Cast iron fronts and backs for :he smaller meters are furnished when desired. The fact that the body (table, partition and channels) is cast in one piece may seem to be unimportant and yet it is a detail of the greatest importancs. This method of construction eliminates machined joints and the use of gaskets between the table, the channels, and the partition, thus preventing any separation of the internal divisions and the consequent interval leakage caused by casting strains, strains produced by bolts or pressure, improper machining of surfaces or broken gaskets between the parts. Meters srith internal leaks may fail, for instance, to meausre the gas used by a pilot light or gas-fired refrigerator. The one-piece design eliminates in a positive mamier Jie possibility of minor internal leaks.
