Abstract
A detection system for determining the level of a liquid in a containment tank includes a containment tank and a reference standard of known weight mounted to the vehicle and movable along the yaw axis of the vehicle. Load cells are placed intermediate the tank and reference standard to provide analog voltage outputs in proportion to the load on each cell. The load cell outputs, when amplified, summed and then divided by the output of the reference weight load cell, provide an electronic signal that is proportional to the gross weight of the tank. A pre-set signal, representative of the empty weight of the tank, is subtracted from the gross weight signal, resulting in a signal which is proportional to the net weight, or the contents of the tank.
