Instruments With a Hollow Displacer or Float
WARNING
For instruments with a hollow liquid level displacer, the displacer might retain process fluid or pressure. Personal injury
and property might result from sudden release of this pressure or fluid. Contact with hazardous fluid, fire, or explosion can
be caused by puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not
be readily apparent when disassembling the sensor or removing the displacer. A displacer that has been penetrated by
process pressure or fluid might contain:
D pressure as a result of being in a pressurized vessel
D liquid that becomes pressurized due to a change in temperature
D liquid that is flammable, hazardous or corrosive.
Handle the displacer with care. Consider the characteristics of the specific process liquid in use. Before removing the
displacer, observe the appropriate warnings provided in the sensor instruction manual.
