4.3 Installation

4.3 Installation
Siemens Level Transmitters with flanged, threaded, or sanitary clamp type process mounts
have no pressure-bearing housing of their own and, therefore, do not come under the
Pressure Equipment Directive as pressure or safety accessories, (see EU Commission Guideline
1/8).
Note
Process device tag
The Process Device Tag shall remain with the process pressure boundary assembly
event the instrument package is replaced, the Process Device Tag shall be transferred to the
replacement unit.
The serial numbers stamped in each process connection body provide a unique identification
number indicating date of manufacture. Example: MMDDYY – XXX (where MM = month, DD
= day, YY = year, and XXX= sequential unit produced). Further markings (space permitting)
indicate flange configuration, size, pressure class, material, and material heat code.
The process pressure boundary assembly comprises the components that act as a barrier
1)
against pressure loss from the process vessel: that is, the combination of process connection
body and emitter, but normally excluding the electrical enclosure.
