Levelflex M FMP40
Endress+Hauser 39
Replacing a displacer system
in an existing displacer
chamber
The Levelflex M is a perfect replacement for a conventional displacer system in an existing displacer chamber.
In addition to the DIN and ANSI flanges, which are available as standard, Endress+Hauser also offers flanges
that suit Fischer and Masoneilan displacer chamber (special product) for this purpose. Thanks to menu-guided
local operation, commissioning the Levelflex M only takes a few minutes. Replacement is also possible when
partially filled, and wet calibration is not required.
Your benefits:
• No moving parts, thus zero-maintenance operation.
• Not sensitive to process influences such as temperature, density, turbulence and vibrations.
• The rod probes can be shortened or replaced easily. In this way, the probe can be easily adjusted on site.

Planning instructions:
• In normal cases, use a rod probe. When installing into a metallic displacer chamber up to 150 mm, you have
all the advantages of a coax probe ("Probe selection", → ä 6).
• It must be ensured that the probe does not come into contact with the side wall. Where necessary, use a
centering disk at the lower end of the probe ("Type of Probe:", → ä 61).
• A centering disk must be adapted as accurately as possible to the internal diameter of the displacer chamber
to also ensure perfect operation in the area of the probe end.
Additional information on interface measurement
• The pipe may not exhibit any steps in diameter. Use the coax probe where necessary.
• In the case of rod probes, it must be ensured that the probe does not come into contact with the wall.
If necessary, use a centering disk at the end of the probe.
Note!
A plastic centering disk has to be used for interface measurement ("Accessories", → ä 65).
