Installation
WARNING
To avoid personal injury or property damage, always wear protective gloves, clothing, and eyewear when performing any
installation operations.
Personal injury or property damage due to sudden release of pressure, 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. Before disassembling the sensor or
removing the displacer, observe the appropriate warnings provided in the sensor instruction manual.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
