API Plan 65A monitors leakage in a single seal arrangement. Connected to the drain port on the gland, a reservoir collects normal leakage and is constantly open to drain. In the event of a seal failure, an orifice fitting on the outlet of the system allows a level transmitter to trigger an alarm due to the excessive leakage.
