6.1.1 Mounting distances
• Distance (A) between wall and rod or rope probe:
– for smooth metallic walls: > 50 mm (2")
– for plastic walls: > 300 mm (12") mm to metallic parts outside the vessel
– for concrete walls: > 500 mm (20") , otherwise the available measuring range may be
reduced.
• Distance (B) between rod or rope probe and internal fittings in the vessel: > 300 mm (12")
• Distance (C) from end of probe to bottom of the vessel: > 10 mm (0.4").

Levelflex FMP51, FMP52, FMP54 Mounting
Endress+Hauser 13
6.1.2 Additional conditions
• When mounting in the open: Use a weather protection cover (1)
• In metallic vessels: Do not mount the probe in the center of the vessel (2).
• Do not mount the probe in the filling curtain (3)
• Avoid buckling the rope probe during installation or operation (e.g. through product movement
against silo wall) by selecting a suitable mounting location.
For coax probes the distance to the wall and to internal fittings is arbitrary.
With suspended rope probes (probe end not fixed at the bottom) the distance between the
probe rope and internal fittings in the tank must not fall below 300 mm (12") during the
entire process. A sporadic contact between the probe weight and the cone of the vessel,
however, does not influence the measurement as long as the dielectric constant of the
medium is at least DC = 1.8.
When mounting the electronics housing into a recess (e.g. in a concrete ceiling), observe
a minimum distance of 100 mm (4 inch) between the cover of the terminal compartment
and the wall.
6.1.3 Installation in horizontal and upright cylindrical tanks
1
2
A0014141
• Any distance from wall, as long as occasional contact is prevented.
• When installing in tanks with a lot of internals or internals situated close to the probe: use a
coax probe.
6.1.4 Wall and pipe mounting
Endress+Hauser offers a mounting bracket for installing the device on pipes or on walls.

6.1.5 Divisible probes
A0014148
If there is little mounting space (distance to the ceiling), it is advisable to use divisible rod probes
(Æ 16 mm).
• max. probe length 10 m/394 inch
• max. sideways capacity 20 Nm
• probes are separable several times with the lengths:
– 500 mm/20 inch
– 1000 mm/ 40 inch
• torque: 15 Nm
6.2 Additional mounting hints
6.2.1 Type of probe installation
• Probes are mounted to the process connection with threaded connections or flanges and are
usually also secured with these. If during this installation there is the danger that the probe
end moves so much that it touches the tank floor or cone at times, the probe must, if necessary,
be shortened and fixed down. The easiest way to fix the rope probes is to screw them to the
internal thread on the lower end of the weight (® ä 19).
• The ideal installation is mounting in a screwed joint / screw-in sleeve which is internally flush
with the container ceiling.
• Alternative: nozzle mounting

Rod extension/centering HMP40 for FMP54
For FMP54 with rope probes the rod extension/centering HMP 40 is available as an accessory .
It has to be used if otherwise the probe rope comes into contact with the lower edge of the
nozzle.
This accessory consists of the extension rod corresponding to the nozzle height, on which
a centering disk is also mounted if the nozzles are narrow or when working in bulk solids.
This component is delivered separately from the device. Please order the probe length
correspondingly shorter.
Only use centering disks with small diameters (DN40 and DN50) if there is no significant
build-up in the nozzle above the disk. The nozzle must not become clogged by the product.
Rod extension/centering HMP40 for FMP57
For FMP57 with rope probes the rod extension/centering HMP 40 is available as an accessory .
It has to be used if otherwise the probe rope comes into contact with the lower edge of the
nozzle.
This accessory consists of the extension rod corresponding to the nozzle height, on which
a centering disk is also mounted if the nozzles are narrow or when working in bulk solids.

• The end of the probe needs to be secured under the following conditions:
if otherwise the probe sporadically comes into contact with the wall of the vessel, the outlet
cone, internal fittings or other parts of the installation.
• The end of probe can be secured at its internal thread
for 4 mm (1/6") rope: M 14
• The fixing must be either reliably grounded or reliably insulated. If it is not possible to mount
the probe weight with a reliably insulated connection, it can be secured using an isolated
eyelet, which is available as an accessory .
• In order to prevent an extremely high tensile load (e.g. due to thermal expansion) and the risk
of rope crack, the rope has to be slack. Make the rope longer than the required measuring
range such that there is a sag in the middle of the rope that is ≥ 1cm/(1 m rope length) [0.12
inch/(1 ft rope length)]. Tensile load limit of rope probes:

• Pipe diameter: > 40 mm (1.6") for rod probes
• Rod probe installation can take place up to a diameter size of 100 mm. In the event of larger
diameters, a coax probe is recommended.
• Side disposals, holes or slits and welded joints that protrude up to approx. 5 mm (0.2") inwards
do not influence the measurement.
• The pipe may not exhibit any steps in diameter.
• The probe must be 100 mm longer than the lower disposal.
• Within the measuring range, the probe must not get into contact with the pipe wall. If
necessary, use a center washer (see feature 610 of the product structure).
• If the center washer is mounted at the end of the probe, it enables a reliable recognition of the
end-of-probe signal (see feature 610 of the product structure). Note: For interface
measurements only use the nonmetallic center washers made of PEEK or PFA (feature 610,
options OD or OE).
• Coax probes can always be applied if there is enough mounting space.
