Benefits
![Faster Trip Time](https://tyco.widen.net/content/cvlzb30jmi/jpeg/bts_icon_benefit_icons_faster_trip_time.jpeg?position=c&color=ffffffff&quality=80&u=ncoxvb)
Deliver water sooner with a quicker, more consistent trip time compared to a mechanical accelerator.
![Reduce False Trips](https://tyco.widen.net/content/djrjhrg1io/jpeg/bts_icon_benefit_icons_reduce_false_trips.jpeg?position=c&color=ffffffff&quality=80&u=ncoxvb)
Active air pressure monitoring adjusts to small and slow changes in pressure system, but trips when there is a steady pressure drop.
