Function and system design
Measuring principle Level measurement
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).
F
L
DE
100%
0%
LN
R
A0014124
LN = probe length R = reference point of measurement
D = distace E = empty calibration (= zero)
L = level F = full calibration (= span)
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).
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 high-frequency 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:
FMP53: (® ä 43)
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.

Levelflex FMP53

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.

Measured variable The measured variable is the distance between the reference point and the product surface.
Subject to the empty distance entered "E" the level is calculated.
Alternatively, the level can be converted into other variables (volume, mass) by means of linearization (32
points).

Blocking distance (factory setting):
with rod probes up to 6 m (20 ft): 200 mm (8 in)
The specified blocking distances are preset on delivery. Depending on the application these settings can
be changed.
When using a spray ball, the blocking distance must be at least 50 mm (2").
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.

!CAUTION
To ensure electrical safety:
►Do not disconnect the protective connection (7).
►Disconnect the supply voltage before disconnecting the protective earth (8).
Connect protective earth to the internal ground terminal (8) before connecting the supply voltage. If
necessary, connect the potential matching line to the external ground terminal (12).
In order to ensure electromagnetic compatibility (EMC): Do not only ground the device via the
protective earth conductor of the supply cable. Instead, the functional grounding must also be
connected to the process connection (flange or threaded connection) or to the external ground
terminal.
An easily accessible power switch must be installed in the proximity of the device. The power switch
must be marked as a disconnector for the device (IEC/EN61010).

Connection examples for the switch output
For HART devices, the switch output is available as an option. See product structure, feature 20:
"Power Supply, Output", option B: "2-wire; 4-20mA HART, switch output"
Devices with PROFIBUS PA and FOUNDATION Fieldbus always have a switch output.

3) For ambient temperatures Ta £ -30 °C (-22 °F) a minimum voltage of 14 V is required for the satrtup of the device
at the MIN error current (3.6 mA). The startup current can be parametrized. If the device is operated with a fixed
current I ³ 4.5 mA (HART multidrop mode), a voltage of 10,4 V is sufficient throughout the entire range of
ambient temperatures.
4) For ambient temperatures Ta £ -30 °C (-22 °F) a minimum voltage of 16 V is required for the startup of the device
at the MIN error current (3.6 mA).

Cable specification HART
•For ambient temperature TU³60 °C (140 °F): use cable for temperature TU +20 K.
•A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended if using the HART protocol. Observe grounding concept of the plant.
PROFIBUS
Use a twisted, screened two-wire cable, preferably cable type A.
For further information on the cable specifications, see Operating Instructions BA00034S "Guidelines
for planning and commissioning PROFIBUS DP/PA", PNO Guideline 2.092 "PROFIBUS PA User and
Installation Guideline" and IEC61158-2 (MBP).
