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:
– Rope probe: > 150 mm (6 in)
– Rod probe: > 10 mm (0.4 in)
6.1.2 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.
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.
6.2 Notes on the process connection
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
(® ä 14).

2 Mounting kit isolated
• 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
rope 4 mm (1/6"), 316: 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 .
6.3.2 Securing rod probes
•For Ex-approvals: For probe lengths ³ 3 m (10 ft) a support is required.
• In general, rod probes must be supported if there is a horizontal flow (e.g. from an agitator)
or in the case of strong vibrations.
• Rod probes may only be supported at the end of the probe.

1Mounting in a stilling well
2 Mounting in a bypass
• 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, FMP51 with 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).
For bypasses with condensate formation (water) and a medium with low dielectric
constant (e.g. hydrocarbons):
In the course of time the bypass is filled with condensate up to the lower disposal and for
low levels the the level echo is superimposed by the condensate echo. Thus in this range
the condensate level is measured instead of the correct level. Only higher levels are
measured correctly. To prevent this, position the lower disposal 100 mm (4 in) below
the lowest level to be measured and apply a metallic centering disk at the height of the
lower edge of the lower disposal.
With heat insulated tanks the bypass should also be insulated in order to prevent
condensate formation.
For rope probes with a length exceeding 2 m (6.7 ft) an additional weight or a spring
should be mounted in addition to the center a washer (option OC) in order to tighten
the rope. The mass of the center wahser is 155 g (5.5 oz).

To measure, Levelflex with a rod probe needs a metallic surface at the process connection.
Therefore:
Mount a metal sheet with a diameter of at least 200 mm (8") to the probe at the process
connection. Its orientation must be perpendicular to the probe.

Requirements
• The dielectric constant of the medium must be at least DC > 7.
• The tank wall must be non-conductvie.
• Maximum wall thickness (a):
– Plastic: < 15 mm (0.6")
– Glass: < 10 mm (0.4")
• There may be no metallic reinforcements fixed to the tank.
Mounting conditions:
• The probe must be mounted directly to the tank wall (no open space)
• A plastic half pipe with a diameter of approx. 200 mm (8"), or some other protective unit,
must be affixed externally to the probe to prevent any influences on the measurement.
• If the tank diameter is less than 300 mm (12"):
A metallic grounding sheet must be installed at the opposite side of the tank. The sheet
must be conductively connected to the process connection and cover about the half of the
vessel's circumference.
• If the tank diameter exceeds 300 mm (12"):
A metal sheet with a diameter of at least 200 mm (8") must be mounted to the probe at the
process connection. Its orientation must be perpendicular to the probe (see above).
Calibration for external probe mounting
If the probe is mounted externally at the wall of the tank, the speed of signal propagation will
be reduced. There are two possibilities to compensate for this effect.
Compensation with the gas phase compensation factor
The effect of the dielectric wall can be compared to the effect of a dielectric gas phase. Thus it
can be compensated for in the same manner. The compensation factor if given by the quotient
of the actual probe length LN and the probe length meausred when the tank is empty.
The device looks for the end of probe signal in the subtracted curve. Thus, the value of
the measured probe length depends on the mapping. In order to obtain an exact value, it
is advisable to determine the probe length manually using the envelope curve display in
FieldCare.

Compensation via the calibration parameters
If an acutal gas phase has to be compensated for, the gas phase compensation functionality is
no longer available for a correction of the external mounting. In this case the calibration
parameters (Empty calibration and Full calibration) must be adjusted and a value longer
than the actual probe length has to be entered into the Present probe length parameter. The
correction factor for these three parameters is given by the quotient of the probe length
measured when the tank is empty and the acutal probe length LN.
