Installation Cerabar M, Deltabar M, Deltapilot M / 4...20 mA HART
20 Endress+Hauser
Installation position for level measurement
Level measurement in an open container
P01-PMD55xxx-11-xx-xx-xx-003
Measuring layout for level measurement in open containers
1 The low-pressure side is open to atmospheric pressure
2Deltabar M
3 Shut-off valve
4 Separator
5 Drain valve
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is always
filled with liquid.
• The low-pressure side is open to atmospheric pressure.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
Level measurement in a closed container
P01-PMD55xxx-11-xx-xx-xx-004
Measuring layout for level measurement in a closed container
1 Shut-off valves
2Deltabar M
3 Separator
4 Drain valves
5 Three-valve manifold
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is always
filled with liquid.
• Always connect the low-pressure side above the maximum level.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
