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).

Levelflex FMP56, FMP57

A0012838

LN = probe length R = reference point of measurement

D = distace E = empty calibration (= zero)

L = level F = full calibration (= span)

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 time­offlight 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

Reference point for "E" see diagram above.

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 wheat, flour etc..

Probe selection

The various types of probe in combination with the process connections are suitable for the following
applications:

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).
