... determined by the maximum variation expected in the system during normal running as a consequence of changing operations and instrument noise. Leak sensitivity is typically determined by the scale of flow and pressure deviations observed in a leak scenario compared to normal operation. Location...

... if the line pressure fell and the differential rate of flow was greater than 2,000 BPD Oil Search performed a leak test on this system in August 1994 with satisfactory results. However, it was accepted that during normal operations of start-up and shutdown, false alarms were experienced. This paper addresses...
