ABSTRACT:
A liquid container is provided with paired variable resistors fluidly connected to the container at opposite ends of the bottom thereof. The resistors are electrically interconnected in series, and the output comprising the sum of the resistances is directly received by an electric current-responsive measuring device. Each of the resistors is weight-responsive and varies individually according to local liquid depth, however, the total resistance for a particular quantity of liquid in the container is always constant. The indicator of the present invention is particularly useful for measuring liquid content in containers subject to movement and change in attitude, such as, for example, gasoline tanks in motor vehicles.
