Abstract
234,515. Krumm, P., and Seignol, E. May 23, 1924, [Convention date]. Indicators actuated by pressure of head of liquid.-The level of a liquid in a vessel, such as the fuel tank of a motor vehicle or aeroplane is indicated upon a gauge the reading of which depends on the pressure head of the liquid upon a pressure transmitting and 'multiplying device which communicates with the gauge. The effect of the pressure head of the liquid upon the flexible underside of a manometric chamber 11, Fig. 1, is communicated to a valve 7 which closes an aperture in a chamber 8 in communication with the gauge 1 and an air compressor 4. When the liquid level in the tank falls, air escapes from the chamber 8 and the reading of the gauge falls. In a modification, the movement of the valve is controlled by a vacuum. In another modification, the pressure head of the liquid ,acts upon a bellows 12, Fig. 3, enclosing a smaller bellows 13 containing a liquid, such as glycerine, the movement of which varies the reading on the gauge.
