ABSTRACT:
An automatic, temperature-compensated liquid or fuel metering device comprises a measuring chamber having a pair of magnetically responsive vertically spaced reed switches therein which are selectively actuated by a magnetcarrying float to control valves associated with the chamber to supply a predetermined increment of liquid to the chamber and thereafter to drain that increment from the chamber into a reservoir. The volume of each increment is dependent upon the spacing between the reed switches, and that spacing is controlled by a bellows having a sample of the liquid being measured sealed therein, the bellows being disposed in the path of flow of liquid to the chamber and being operative to vary the volume of said increments with variations in the temperature of the liquid being measured.
