Levelflex M FMP40 FOUNDATION Fieldbus Mounting
Endress+Hauser 25
Measurement in corrosive fluids
For measurement in corrosive liquids use Levelflex M FMP41C. When using plastic tanks it is also
possible to mount the probe on the outside of the tank (Installation instructions, → ä 28). Levelflex
measures the level through the plastic in both cases.
Installation in underground tanks
Use coax probe for nozzles with large diameters
in order to avoid reflections at the nozzle wall.

Installation in stilling well or bypass
• A rod probe can be used for pipe diameters
bigger than 40 mm.
• When installing a rod probe into a metallic
pipe with internal diameter of up to 150 mm,
you have all the advantages of a coax probe.
• Welded joints that protrude up to approx.
5 mm (0.2") inwards do not influence
measurement.
• If a rod probe is used, the probe length must
be 100 mm longer than the lower disposal.
• 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 8)
