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 (0 to 9.84 in) from end of probe; lower blocking distance).

Levelflex FMP56, FMP57
Endress+Hauser 7
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:
• FMP56: →  61
• FMP57: →  62
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.

Measuring system General notes on probe selection
• Normally, rope probes should be used for bulk solids, rod probes are only suitable for short
measuring ranges up to approx. 2 m (6.6 ft) in bulk solids. This applies above all to applications in
which the probe is installed laterally at an angle and for light and pourable bulk solids.
• In the case of large silos, the lateral pressure on the rope can be so high that a rope with plastic
jacketing must be used. We recommend PA-coated ropes be used for cereal products such as
wheat, flour etc.
Probe selection
The various types of probe in combination with the process connections are suitable for the following
applications 1):

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).
Measuring range The following table describes the media groups and the possible measuring range as a function of
the media group.

SD Safety distance
Blocking distance (factory setting):
• 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.
