Apparatus for measuring the amount of liquid in a tank mounted within a vehicle by measuring the tank pivot cell and inclinometer

An apparatus for measuring the amount of liquid in a tank mounted within a vehicle, said apparatus comprising:

• a tank-mount mechanically coupled to and surrounding said tank to prevent translational movement of said tank, said tank-mount including
• a plurality of pivoting members allowing only rotational movement of said tank, said members pivoting about a common axis, defined by an orifice of each of a plurality of fixed members that are mechanically coupled to the vehicle. and
• an extended end positioned on a side opposite to said plurality of pivoting members which extends outwardly from said tank;
• a load cell in contact with said extended end for providing a first signal proportional to a force F.sub.s placed on said load cell by said extended end;
• a Central Processing Unit in electrical communication with said load cell, and which processes the first signal from said load cell and calculates the amount of the liquid in said tank based on the force F.sub.s on said load cell, a distance A from the center of gravity of said tank to the common axis, and a distance B from the common axis to where said extended end applies the load F.sub.s to said load cell such that the actual weight FT of the tank and the fluid is calculated by the equation FT=(B/A).times.(F.sub.s);
• and
• an inclinometer electrically coupled to said Central Processing Unit, said inclinometer transmitting a second signal to said Central Processing Unit directly proportional to the angle of inclination of the vehicle, wherein said Central Processing Unit processes the second signal and adjusts the relationship between the total weight of said tank and the force registered by the load cell accordingly.
