Abstract

Precision gauge for liquid fuel in a vehicle'"'"'s tank, based on the usage of electronic scales, a computer, the odometer and an electronic circuit based on the tank weight previous to the loading (Weight 1), density of the used fuel (previously digitized in the computer) and the weight of the tank after loading it (Weight 2); allows visualizing by means of a proper device (digital display), the volume of fuel contained in such tank, VOLUME_=(Weight 2−Weight 1)/DENSITY and eventually to appreciate the amount of fuel consumed by the vehicle per unit of time and/or per kilometer covered.

Claims

1. Precision gauge for liquid fuel in a vehicle'"'"'s tank characterized for containing:

a precision electronic scales which is connected to the vehicle'"'"'s fuel tank;

a computer that based on—

as first information—

the fuel tank'"'"'s weight with its contents previous to the loading (Weight 1), and on the information received form the scales (weight of the tank after loading, Weight 2), and on the corresponding density previously entered in the computer (maybe just once per vehicle);

determines the volume of loaded up fuel that can be noticed in a display (digital display) located in the vehicle'"'"'s board. Resultant form the mathematic relation between weight, volume and density (Vol=(Weight 2−

Weight 1)/density);

an electronic circuit linking the different components of the device.

2. Precision gauge for liquid fuel in a vehicle'"'"'s tank according to claim 1, characterized for including:

a mechanical, electric or electric-mechanical device that if necessary, while the car is on, from controls located next to the driver, releases the mechanical link between scales and fuel.

3. Precision gauge for liquid fuel in a vehicle'"'"'s tank according to claim 1, characterized for:

the computer, based on the evolution of the reduction of fuel weight, reports about the consumption per unit of time and/or per kilometer covered.
