Abstract
A flow meter, particularly applicable to the instantaneous measurement of an automobile vehicle's fuel consumption, includes an enclosure separated into two chambers by a flexible membrane which operates in conjunction with compression springs. The fuel enters the bottom chamber and, in the top chamber, goes through a pipe which provides a calibrated pressure drop. A pick-up measures the resultant membrane movements.
