• When air flows, the indicator is activated!
• When air flows, the indicator will activate and continue to display until it is manually released.
• Unlike a typical flow monitor, you can check whether the air has flowed later.
• The tip of the indicator needle is magnetic and is released when the upper magnet is removed.
• When combined with safety mechanisms such as leak valves and backup flow channels, it can be used as a detector for its operation.
