Abstract
The rate of fuel consumption of a vehicle is measured by an apparatus which measures the distance traveled by the vehicle during the consumption of a fixed quantity of fuel. A linkage unit in series with the odometer cable produces electrical pulses, which drive a counter in direct relation to the distance traveled. A fuel flow sensor unit is inserted in the fuel line between the fuel pump and the fuel flow regulator of the vehicle engine. The sensor includes a U-tube partially filled with an electrolyte. As fuel is consumed by the engine, the electrolyte rises in one arm of a U-tube. The counter is turned on and then turned off as the electrolyte rises to the level of one and then another metallic contact in the tube. The distance between the contacts and the cross section area of the tube determines the fixed volume of fuel. The number of pulses counted determines the distance traveled during the consumption of the fixed volume of fuel. Appropriate design of the linkage unit and the sensor unit makes the counter read directly in the desired units of fuel consumption rate (e.g. miles per gallon). An exemplary device has been constructed which is direct reading in tenths of a mile per gallon.
