  • Method for proportioning fuel usage by a fluid fueled apparatus
    Patent number: 4565207
    Abstract: A fluid proportioning system for apportioning fuel usage among several discrete fluid fuel supplies which are used to supply fluid fuel to a single commonly used apparatus. An application for the invention is in a multidwelling unit wherein each unit is heated from a common furnace. Each tenant's metered gas line is tapped in proportion to the amount of heat necessary to heat their dwelling unit by the adjustment of precision valves, the gas from each line being combined in a manifold. Means are provided to preclude interaction of the individually metered gas lines when the furnace is not consuming gas.
