Farris SmartPRV technology is a simple, powerful solution to improve your ability to monitor critical safety valve and their effects on plant performance.
Overpressure events are unpredictable, can go unnoticed and consequently can be difficult to estimate.
Using the SmartPRV system, facilities are not able to record over pressure events.
SmartPRV provides
Equipped plants with the ability to track and monitor valves in real time
Provides immediate feedback during an overpressure event
Feedback includes the time and duration of the overpressure event
Allowing plants to more accurately estimate releases
