ABSTRACT:
A device, and a container having such a device, is provided for permitting filling the container with a predetermined weight of the fluid. The device and container include a main channel to introduce the fluid into the container at a fill pressure; a detector mechanism to detect a "filled" condition based on fluid weight; and a fluid-weight control mechanism to automatically prevent introducing fluid into the container in excess of the "filled" condition. A spring offsets part of the weight of a pivotally mounted displacer mounted on a pivotally mounted lever having an arm configured to permit closure of a ball valve as the container becomes "filled" and the displacer becomes buoyant. The fluid-weight control device, which is substantially independent of the composition and temperature of the fluid and of inertial effects induced in an attempt to thwart the fluid-weight control safeguard, also prevents introduction of fluid into the container as the container is non-upright. A modified embodiment utilizes a pilot valve arrangement in conjunction with the ball valve. A method of practicing the invention is also provided.
