2.1 Mounting instructions PMP 71 K
The Cerabar S is mounted in the same way as a manometer (DIN EN 839-2). The use of
shut-off valves and pigtails is recommended. Its position depends upon the application.
•
Measurement in gases:
Mount the shut-off valve above the
tapping point so that condensate can
run back into the process.
•
Measurement in steam:
Mount with a pigtail below the tapping
point.
The pigtail reduces the temperature in
front of the diaphragm to almost
ambient temperature. The pigtail must
be filled with fill fluid before start-up.
