API Plan 65B Leakage Collection with Reservoir
API Plan 65B monitors leakage in a single seal arrangement. Connected to the drain port on the gland, a reservoir is allowed to collect normal leakage. A level transmitter on the reservoir triggers an alarm in the event of excessive leakage. A valve on the outlet side of the reservoir is typically left closed and is only opened periodically to drain the reservoir.
