Sight flow indicators show media (e.g., gas, liquid, vapor, powder) moving through a system and ensure systems work as intended. These indicators are installed in line with the system's plumbing or pipe segment and require minimal line alterations which limits drops in system line pressure. Full-view sight glass flow indicators have straight, cylindrical viewing glasses to provide complete visual coverage of fluids traveling through a system. Window-style sight glass flow indicators have viewing panes for observing and showing the flow of media in a system.
