Abstract:
A method for measuring the volume of a liquid in a fuel tank in a vehicle that is subject to varying external forces caused by movement or charges in the roll and pitch of the vehicle, comprising the steps of:conducting a plurality of measurements, each measurement including the known volume of the tank and the value of at least three parameters concerning the tank, said parameters being selected from the group consisting of the load of the tank on a load cell arranged at a first location, the load of the tank on a load cell arranged at a second location, the load of the tank at a load cell arranged at a third location, the pitch angle of the vehicle, the roll angle of the vehicle, the height of the fuel at a first location in the tank, the height of the fuel at a second location in the tank and the height of the fuel at a third location in the tank, generating an algorithm from said plurality of measurements for determining the volume of fuel in the tank upon the receipt of current values of said at least three parameters, inputting said algorithm into processor means arranged in connection with the vehicle, measuring said at least three parameters during operation of the vehicle, and inputting said at least three parameters into said algorithm in said processor means such that said algorithm provides the volume of fuel in the tank.
