Hydrostatic Monitor-When a hydrostatic <br /> monitoring system is used, the level of <br /> liquid in the reservoir may be monitored to <br /> detect a leak in either the inner or outer <br /> wall of the tank. <br /> b. vacuum Monitor—When vacuum Duplex Tank-Wall Fittings <br /> monitoring is used, a maximum of 3" Duplex fittings allow for the placement of two fittings in one <br /> mercury(I.5 psi maximum) must be <br /> maintained. location.
