6.1 Mounting requirements

A0021468
4Mounting requirements for Levelflex
Mounting distances
• Distance (A) between wall and rod or rope probe:
– for smooth metallic walls: > 50 mm (2 in)
– for plastic walls: > 300 mm (12 in) to metallic parts outside the vessel
– for concrete walls: > 500 mm (20 in), otherwise the available measuring range may be
reduced.
• Distance (B) between rod or rope probe and internal fittings in the vessel: >
300 mm (12 in)
• When using more than one Levelflex:
Minimum distance between the sensor axes: 100 mm (3.94 in)
• Distance (C) from end of probe to bottom of the vessel:
– Rope probe: > 150 mm (6 in)
– Rod probe: > 10 mm (0.4 in)
20Endress+Hauser
Levelflex FMP56, FMP57 PROFIBUS PAMounting
Additional conditions
• When mounting in the open, a weather protection cover (1) may be installed to protect
the device against extreme weather conditions.
• In metallic vessels: Preferably do not mount the probe in the center of the vessel (2), as
this would lead to increased interference echoes.
If a central mounting position can not be avoided, it is crucial to perform an interference
echo suppresion(mapping) after the commissioning of the device.
• 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.
• Check the probe regularly for defects.
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 / electronics compartment and the wall. Otherwise the connection
compartment / electronics compartment is not accessible after installation.

6.1.2 Applications with restricted mounting space
Mounting with remote sensor
The device version with a remote sensor is suited for applications with restricted mounting
space. In this case the electronics housing is mounted at a separate position from which it
is easier accessible.
A0014794
AAngled plug at the probe
BAngled plug at the electronics housing
CLength of the remote cable as ordered
• The remote cable is supplied with these device versions
Minimum bending radius: 100 mm (4 inch)
• A mounting bracket for the electronics housing is supplied with these device versions.
Mounting options:
– Wall mounting
– Pipe mounting; diameter: 42 to 60 mm (1-1/4 to 2 inch)
• The connection cable has got one straight and one angled plug (90°). Depending on the
local conditions the angled plug can be connected at the probe or at the electronics
housing.
Probe, electronics and connection cable are adjusted to match each other. They are
marked by a common serial number. Only components with the same serial number
shall be connected to each other.
Since the tensile forces are also heavily dependent on the viscosity of the product, a higher
safety factor is necessary for highly viscous products and if there is a risk of cornice
buildup. In critical cases it is better to use a 6 mm rope instead of a 4 mm one.
The same forces also act on the silo cover. On a fixed rope, the tensile forces are definitely
greater, but this can not be calculated. Observe the tensile strength of the probes.
Options for reducing the tensile forces:
• Shorten the probe.
• If the maximum tensile load is exceeded, check whether it would be possible to use a
non-contact Ultrasonic or Level-Radar device.
The following diagrams show typical loads for frequently occurring bulk solids as reference
values. The calculation is performed for the following conditions:
• Calculation according to DIN 1055, Part 6 for the cylindrical part of the silo.
• Suspended probe (probe end not fixed at the bottom)
• Free-flowing bulk solid, i.e. mass flow. A calculation for core flow is not possible. In the
event of collapsing cornices, considerably higher loads can occur.
• The specification for tensile forces contains the safety factor 2 (in addition to the safety
factors already taken into account by DIN 1055), which compensates for the normal
fluctuation range in pourable bulk solids.

Probes are mounted to the process connection with threaded connections or flanges. 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 → 31.

The thread as well as the type of seal comply to DIN 3852 Part 1, screwed plug form A.
They can be sealed with the following types of sealing rings:
• Thread G3/4": According to DIN 7603 with the dimensions 27 x 32 mm
• Thread G1-1/2": According to DIN 7603 with the dimensions 48 x 55 mm
Please use a sealing ring according to this standard in the form A, C or D and of a material
that is resistant to the application.

For larger diameters the near range measuring capability may be reduced.
For nozzles ≥ DN300: → 30.

: ≤ 150 mm (6 in).
For a larger height the near range measuring capability may be reduced.
Larger nozzle heights may be possible in special cases (see section "Rod extension/
centering HMP40 for FMP57").
• The end of the nozzle should be flush with the tank ceiling in order to avoid ringing
effects.
With thermally insulated vessels the nozzle should also be insulated in order to
prevent condensate formation.

Rod extension/centering HMP40 for FMP57
For FMP57 with rope probes the rod extension/centering HMP 40 is available as an
accessory → 96. It has to be used if otherwise the probe rope comes into contact with
the lower edge of the nozzle.
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. This component is delivered separately from the device. Please order the
probe length correspondingly shorter.
Centering disks with small diameters (DN40 and DN50) may only be used if there is
no significant build-up in the nozzle above the disk. The nozzle must not become
clogged by the product.
