Machine for testing container capacity

摘要

An inspection machine for inspecting the volume of liquid contained by a bottle filed to its defined fill height. A head is lowered and has a sealing plate which seals the open finish of a bottle. A fill tube assembly is part of the head and continues to be lowered until a level sensor is located to sense liquid at a pre-fill level. High and low pressure water lines which are a part of the fill tube assembly are operated to fill the bottle to the pre-fill level. The sealing plate is released and then the process is repeated lowering the sensor to the post-fill level and operating only the low-pressure line to fill the bottle to the post-fill level. The total liquid filling the bottle is then computed.
