Mounting instructions without diaphragm seal
Barcon
without diaphragm seal
– PPC-M10, PPC-M20
– LHC-M20
The Barcon without diaphragm seal is mounted in the same way as a manometer. The
use of shut-off valves and pigtails is recommended. The 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 above the tapping point.
The pigtail reduces the temperature in front of the diaphragm to almost
ambient temperature. Before start-up, the pigtail must be filled with water.
