Title: Domestic Meters
Author: H. V. Beck

Abstract: Domestic gas meters are commercial devices which constitute a functional blend of laboratory instruments, piping equipment and billing machines. These devices must be rugged, accurate to what really are extreme limits - from pilot light rates to full badged capacity, and be capable of retaining that accuracy for 15 or 20 years without servicing or other attention. They measure an elastic fluid whose volume is constantly varying with pressure and temperature, and which fluid might contain some contaminants -either from its original composition, or purposely added to allay main dust, seal pipe joints, or to give to the odor desirable to identify possible leakage. Gas meters may be installed in quite inaccessible locations indoors, or when outdoors, they may encounter widely fluctuating temperature, from winter temperatures of 40 below zero to 140 above-when absorbing the direct sunshine of a summer day. They must do all this, be inexpensive, and still be esthetic in design and capable of installation so as not to detract from the well-kept premises of the gas companys customer.
