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

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.
