Float gauge with fixed liquid level gauge

摘要

A head for use in a combination float and maximum liquid level gauge. The head has a receptacle for receiving the support member of a float gauge and contains a passageway one end of which is positioned so that it will be exposed to the interior of a LP gas vessel and the other end of a passageway is external of the LP gas container. The exterior end is closed by a valve. The head may be used in conjunction with a dip tube, a float gauge, or a float gauge which has been modified to function as a dip tube to provide a combination fixed liquid level and float gauge.
