Installation Cerabar M, Deltabar M, Deltapilot M / 4...20 mA HART
22 Endress+Hauser
Installation position for differential pressure measurement
Differential pressure measurement in gases and steam
P01-PMD55xxx-11-xx-xx-xx-006
Measuring layout for differential pressure measurement in gases and steam
1Deltabar M
2 Three-valve manifold
3 Shut-off valves
4 e.g. filter
• Mount the Deltabar M above the measuring point so that the condensate which may be present,
can run off into the process piping.
Differential pressure measurement in liquids
P01-PMD55xxx-11-xx-xx-xx-007
Measuring layout for differential pressure measurement in liquids
1 e.g. filter
2 Shut-off valves
3Deltabar M
4 Separator
5 Drain valves
6 Three-valve manifold
• Mount the Deltabar M below the measuring point so that the impulse piping is always filled with
liquid and gas bubbles can run back into the process piping.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
