Use:

Visual survey of flow and filling processes in piping. The sight glasses allow for a reliable observation of function and performance of single devices or complete plants. With this design, no significant amount of liquid will remain in the sight glass when installed horizontally. With standard sight glasses, liquid will remain in the sight glass body. This liquid will drain out with this design.
