Abstract
The specification and drawings disclose a gauge glass assembly including a gauge glass protected by a tubular shield including means for permitting visual observation of the gauge glass. The gauge glass is positioned in a cylindrical receptor which is in flow communication with the liquid whose level is being observed. The shield surrounds the gauge glass and has a length sufficient to enclose the exposed length of gauge glass. At the upper end of the shield an upper nut member is threadedly received on the shield and arranged such that when tightened it applies an axially directed force to drive the glass into the receptor. A lower nut member is positioned about the lower end of the gauge but is threaded to the receptor. Outwardly extending tabs or ears on the shield are engaged by the lower nut such that tightening of the nut drives the shield axially toward the receptor.
