Abstract
A fuel measuring system which accurately measures fuel consumed by a vehicle and the distance traveled by the vehicle and provides a detectable signal of distance traveled per quantity of fuel consumed. The system includes a valve with a reservoir which measures fuel flow from the fuel pump. A speed sensor provides a signal indicative of a given distance traveled by the vehicle. The number of times the reservoir is filled and unfilled with fuel is compared via a logic circuit with a signal from the speed sensor to provide a detectable readout of distance traveled by the vehicle per quantity of fuel consumed. A valve may be used by itself to measure fluid flow in a given passage.
