Function and system design
Measuring principle
Basic principles
The Levelflex is a "downward-looking" measuring system that functions according to the ToF method
(ToF = Time of Flight). The distance from the reference point to the product surface is measured.
High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by
the product surface, received by the electronic evaluation unit and converted into level information.
This method is also known as TDR (Time Domain Reflectometry).

If, for rope probes, the DC value is less than 7, then measurement is not possible in the area of
the straining weight (0 to 250 mm from end of probe; lower blocking distance).

Endress+Hauser
Levelflex FMP51, FMP52, FMP54
Dielectric constant
The dielectric constant (DC) of the medium has a direct impact on the degree of reflection of the
highfrequency pulses. In the case of large DC values, such as for water or ammonia, there is strong
pulse reflection while, with low DC values, such as for hydrocarbons, weak pulse reflection is
experienced.
Input
The reflected pulses are transmitted from the probe to the electronics. There, a microprocessor
analyzes the signals and identifies the level echo which was generated by the reflection of the highfrequency pulses at the product surface. This clear signal detection system benefits from over 30
years' experience with pulse time-of-flight procedures that have been integrated into the
development of the PulseMaster® software.
The distance D to the product surface is proportional to the time of flight t of the impulse:
D = c · t/2,
where c is the speed of light.
Based on the known empty distance E, the level L is calculated:
L=E–D
The reference point R of the measurement is located at the process connection. For details see the
dimensional drawing:
• FMP51: (→  81)
• FMP52: (→  84)
• FMP54: (→  85)
The Levelflex possesses functions for interference echo suppression that can be activated by the user.
They guarantee that interference echoes from e.g. internals and struts are not interpreted as level
echoes.
Output
The Levelflex is preset at the factory to the probe length ordered so that in most cases only the
application parameters that automatically adapt the device to the measuring conditions need to be
entered. For models with a current output, the factory adjustment for zero point E and span F is 4
mA and 20 mA, for digital outputs and the display module 0 % and 100 %. A linearization function
with max. 32 points, which is based on a table entered manually or semi-automatically, can be
activated on site or via remote operation. This function allows the level to be converted into units of
volume or mass, for example.

Levelflex FMP51, FMP52, FMP54
Interface measurement
When the high-frequency pulses hit the surface of the medium, only a percentage of the
transmission pulse is reflected. In the case of media with a low DC1, in particular, the other part
penetrates the medium. The pulse is reflected once more at the interface point to a second medium
with a higher DC2. The distance to the interface layer now can also be determined taking into
account the delayed time-of-flight of the pulse through the upper medium.

In addition, the following general conditions must be observed for interface measurement:
• The DC of the upper medium must be known and constant. The DC can be determined with the aid
of the DC manual CP00019F. In addition, if the interface thickness is existing and known, the DC
can be calculated automatically via FieldCare.
• The DC of the upper medium may not be greater than 10.
• The DC difference between the upper medium and lower medium must be >10.
• The upper medium must have a minimum thickness of 80 mm.

Measuring system
General notes on probe selection
• Normally use rod or coax probes for liquids. Rope probes are used in liquids for measuring ranges >
10 m (33 ft) ( > 4 m (13 ft) for FMP52) and with restricted ceiling clearance which does not allow
the installation of rigid probes.
• For interface measurement, ideally coax probes or rod probes in a bypass/stilling well are used.
• Coax probes are suited to liquids with viscosities of up to approx. 500 cst. Coax probes can measure
most liquefied gases, as of a dielectric constant of 1.4. Moreover, installation conditions, such as
nozzles, tank internal fittings etc., have no effect on the measurement when a coax probe is used.
A coax probe offers maximum EMC safety when used in plastic tanks.

Safety distance
Blocking distance (factory setting):
• with coax probes: 0 mm (0 in)
• with rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
• with rod and rope probes exceeding a length of 8 m (26 ft): 0.025 * (length of probe)
The specified blocking distances are preset on delivery. Depending on the application these
settings can be changed.
For rod and rope probes and for media with DC > 7 (or generally for stilling well/bypass
applications) the blocking distance may be reduced to 100 mm (4").
Within the blocking distance, a reliable measurement can not be guaranteed.
A safety distance SD can be defined in addition to the blocking distance. A warning is generated
if the level rises into this safety distance.

Influence of gas layer
Gas layer

Water
(saturated

High pressures reduce the propagation velocity of the measuring signals in the gas/vapor above the
fluid. This effect depends on the kind of gas/vapor and of its temperature. This results in a
systematic measuring error that gets bigger as the distance increases between the reference point of
the measurement (flange) and the product surface. The following table illustrates this measured
error for a few typical gases/vapors (with regard to distance; a positive value means that too large a
distance is being measured):

Gas phase compensation
with external pressure
sensor (PROFIBUS PA /
FOUNDATION Fieldbus)
Endress+Hauser
PROFIBUS and FOUNDATION Fieldbus devices can receive the signal of an external pressure sensor
through the bus and use it to perform a pressure dependent time-of-flight correction. In the case of
saturated steam in the temperature range from 100 to 350 °C (212 to 662 °f), for example, the
measuring error of the distance measurement can be reduced by this method from up to 29 %
(without compensation) to less than 3 % (with compensation).

Under high pressure the propagation speed of microwave signals is reduced in the steam (polar
media) above the liquid to be measured. As a result, the Levelflex indicates the level too low
(→  41).

As an option Levelflex is available in a version with automatic gas phase correction, which corrects
this error (feature 540 "Application Package", option EF: "Gas Phase Compensation Lref= 300 mm" or
EG: "Gas Phase Compensation Lref= 550 mm"). This version of the Levelflex generates a reference
reflection in the distance Lref from the flange by a diameter step of the probe rod. The reference
reflection must be at least 150 mm (6") above the highest level. By means of the shift of the
reference reflection the actual propagation speed is measured and the level value will be
automatically corrected.

Coax probes with reference reflection can be installed in any tank (free in the tank or into a
bypass). Coax probes are completely mounted and adjusted ex works. After mounting they are
ready for use, additional settings are not necessary.
Rod probes are only recommended if the installation of a coax probe is not possible (e.g. if the
bypass diameter is too small).
Rod probes with reference reflection are only suited for mounting in stilling wells and side
gauges (bypasses). The diameter Dref of the probe rod in the range of the reference distance Lref
must be chosen depending on the pipe inner diameter iD, see table below. In the range of the
reference distance Lref the pipe has to be cylindrical; changes of the cross section, for example at
flanged connections, are only allowed up to 5% of the inside diamter iD.
Additionally, the settings must be checked by an expert person after mounting and corrected if
necessary.

If there are fast changes in pressure, there may be an additional error, since the mesured reference
distance is filtered with the time constant of the level measurement. In addition, conditions of
imbalance - for example due to heating - may cause density gradients within the medium and
condensation of steam at the probe. As a result, the level readings at different locations inside the
tank may vary slightly. Caused by this application influences the measuring error may be increased
by a factor up to 2 to 3.

Mounting requirements for Levelflex
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)
– Coax probe: > 10 mm (0.4 in)
For coax probes the distance to the wall and to internal fittings is arbitrary.
44
Endress+Hauser
Levelflex FMP51, FMP52, FMP54
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.

• Pipe diameter: > 40 mm (1.6") for rod probes
• Rod probe installation can take place up to a diameter size of 150 mm (6 in). 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 or centering star (see feature 610 of the product structure).
• If the center washer or centering star 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 centering star made of PEEK or PFA
(feature 610, options OD or OE).
• Coax probes can always be applied if there is enough mounting space.
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).

• 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).

Replacing a displacer system in an existing displacer chamber
FMP51 and FMP54 are a perfect replacement for a conventional displacer system in an existing
displacer chamber. Endress+Hauser offers flanges that suit Fischer and Masoneilan displacer
chamber for this purpose (special product for FMP51; feature 100, options LNJ, LPJ, LQJ for FMP54).
Thanks to menu-guided local operation, commissioning the Levelflex 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.

Flange of the displacer chamber
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.
• It must be ensured that the probe does not come into contact with the side wall. Where necessary,
use a center washer or centering star at the lower end of the probe (feature 610 of the product
structure).
• The center washer or centering star 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
• In the case of oil and water the centering disk or centering star should be positioned at the lower
edge of the lower disposal (water level).
• 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 center washer or centering star at the end of the probe.
• A plastic centering star has to be used for interface measurement (feature 610, options OD and
OE).

Cleaning the probe
Depending on the application, contamination or buildup can accumulate on the probe. A thin, even
layer only influences measurement slightly. Thick layers can dampen the signal and then reduce the
measuring range. Severe, uneven buildup, adhesion e.g. through crystallization, can lead to incorrect
measurement. In this case, we recommend that you use a non-contact measuring principle, or check
the probe regularly for soiling.
Electromagnetic
compatibility (EMC)
Electromagnetic compatibility to all relevant requirements of the EN 61326- series and NAMUR
recommendation EMC (NE21). For details see declaration of conformity. 9). If only the analogue
signal is used, unshielded interconnection lines are sufficient for the installation. In case of using the
digital signal (HART/ PA/ FF) use shielded interconnection lines.
Use a shielded cable when working with a digital communications signal.
Max. fluctuations during EMC- tests: < 0.5 % of the span.
When installing the probes in metal and concrete tanks and when using a coax probe:
• Interference emission to EN 61326 - x series, electrical equipment Class B.
• Interference immunity to EN 61326 - x series, requirements for industrial areas and NAMUR
Recommendation NE 21 (EMC)
The measured value can be affected by strong electromagnetic fields when installing rod and rope
probes without a shielding/metallic wall, e.g. in plastic and wooden silos.
• Interference emission to EN 61326 - x series, electrical equipment Class A.
• Interference immunity: the measured value can be affected by strong electromagnetic fields.

Recommended for steam applications
Not recommended for saturated steam above 150 °C (302 °F). Use FMP54 instead.
Plastic parts in contact with process have been tested according to USP <88> Class VI-70°C.
Not recommended for saturated steam above 200 °C (392 °F). Use the HT version instead.
With uncoated probes, the medium temperature may be higher, under the condition that the
maximum process temperature specified in the table above is not exceeded at the process
connection.
However, when using rope probes, the stability of the probe rope is reduced by structural
changes at temperatures above 350 °C (662 °F).

Surface roughness of AlloyCcoated flanges
Ra = 3.2 μm; lower surface roughness levels are available on request.
Shortening probes
If necessary, probes can be shortened. When doing so, the following must be observed:
This value is valid for flanges with "AlloyC>316/316L"; see product structure, feature 100 "Process
connection". For other flanges the surface roughness matches the corresponding flange standard.
Shortening rod probes
Rod probes must be shortened if the distance to the container floor or outlet cone is less than
10 mm (0.4 in). The rods of a rod probe are shortened by sawing at the bottom end.
Rod probes of FMP52 can not be shortened as they are coated.
Shortening rope probes
Rope probes must be shortened if the distance to the container floor or outlet cone is less than
150 mm (6 in).
Rope probes of FMP52 can not be shortened as they are coated.
Shortening coax probes
Coax probes must be shortened if the distance to the container floor or outlet cone is less than
10 mm (0.4 in).
Coax probes can be shortened max. 80 mm (3.2 in) from the end. They have centering units
inside, which fix the rod centrally in the pipe. The centerings are held with borders on the rod.
Shortening is possible up to approx. 10 mm (0.4 in) below the centering unit.

Integration in tank gauging
system
The Endress+Hauser Tank Side Monitor NRF590 provides integrated communications for sites with
multiple tanks, each with one or more sensors on the tank, such as radar, spot or average
temperature, capacitive probe for water detection and/or pressure sensors. Multiple protocols out of
the Tank Side Monitor guarantee connectivity to nearly any of the existing industry standard tank
gauging protocols. Optional connectivity of analog 4...20 mA sensors, digital I/O and analog output
simplify full tank sensor integration. Use of the proven concept of the intrinsically safe HART bus for
all on-tank sensors yields extremely low wiring costs, while at the same time providing maximum
safety, reliability and data availability.

System integration via
Fieldgate
Vendor Managed Inventory
By using Fieldgates to interrogate tank or silo levels remotely, suppliers of raw materials can provide
their regular customers with information about the current supplies at any time and, for example,
account for them in their own production planning. For their part, the Fieldgates monitor the
configured level limits and, if required, automatically activate the next supply. The spectrum of
options here ranges from a simple purchasing requisition via e-mail through to fully automatic order
administration by coupling XML data into the planning systems on both sides.
Remote maintenance of measuring equipment
Fieldgates not only transfer the current measured values, they also alert the responsible standby
personnel, if required, via e-mail or SMS. In the event of an alarm or also when performing routine
checks, service technicians can diagnose and configure connected HART devices remotely. All that is
required for this is the corresponding HART operating tool (e.g. FieldCare, ...) for the connected
device. Fieldgate passes on the information transparently, so that all options for the respective
operating software are available remotely. Some on-site service operations can be avoided by using
remote diagnosis and remote configuration and all others can at least be better planned and
prepared.

The centering star is suitable for probes with a rod diameter of
16 mm (0.6 in) and can be used in pipes from DN40 (1½") up to
DN100 (4"). Markings on the 4-leg centering star ensure a simple
tailoring. Hence the centering star can be adapted to the pipe diameter.

Admissible process temperature: –60 to +200 °C (–76 to +392 °F)
Order code: 71069064
If the centering star is inserted in a bypass, it must be positioned
below the lower bypass outlet. This has to be accounted for when
choosing the probe length. Generally, the centering star should
not be mounted higher than 50 mm (1.97") from the probe end.
It is recommended not to insert the PEEK centering star in the
measuring range of the rod probe.
The PEEK centering star can also be ordered directly with the
device (see the Levelflex product structure, feature 610
"Accessory mounted", option OD). In this case it is not fastened by
the retaining rings. Instead it is fixed to the end of the probe rod
by a hexagonal headed bolt (A4-70) and a Nord-Lock washer
(1.4547).
