Abstract
255,705. Spitzglass, J. M. Nov. 24, 1925. Liquid - level pressure gauges. - The maximum demand by a customer for gas or other fluid during a given period is indicated by measuring the maximum difference of level between balance columns of liquid, the columns being subject to the pressures existing at different points in the fluid-supply conduit. In the Figure one leg 21 of a U-tube 13 containing mercury is connected directly to the inlet pipe 11 of an ordinary gas meter 10 and the other leg 22 opens into a vessel or chamber 15 which is connected by a pipe 16 to the outlet pipe 12 of the meter. When gas is being consumed the fall of pressure across the meter causes the mercury to rise in the leg 22 and provided that the demand is not merely momentary the mercury escapes through small perforations 23 into the chamber 15 and overflows into a graduated tube 17. The mercury overflowing into the tube 17 during a given period indicates the maximum demand during that period. The tube 17 is connected to the chamber 15 by a bushing 19 which allows it to be elevated and the mercury in it returned to the U-tube 13 when the instrument is required to be re-set for a new period.
