Levelflex M FMP43

Function and system design

Measuring principle 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 (process connection of the measuring device, → ä 26)
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).

L00-FMP43xxx-15-00-00-en -001

Reference point of measurement, details → ä 26

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 analyses 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 finding benefits from the more than 30 years of experience with pulse time­of-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 pulse:

D = c · t/2,
with "c" being the speed of light.

Based on the known empty distance "E", the level "L" is calculated:

L = E – D

Reference point for "E" see above diagram.

The Levelflex possesses functions for the 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 initially adjusted 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 current output, the factory adjustment for zero point "E" and span is "F" 4 mA and 20 mA.
For digital outputs and the display module, the factory adjustment for zero point "E" and span "F" is 0 % and
100 %. A linearization function with max. 32 points, that is based on a manually or semi-automatically input
table, can be activated onsite or via remote operation. This function enables, for example, the conversion of
the level into units of volume or weight.

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 software (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
onsite service operations can be avoided by using remote diagnosis and remote configuration and all others can
at least be better planned and prepared.

Input

Measured variable The measured variable is the distance between the reference point (see Fig, → ä 26) and the product surface.

Subject to the input zero point empty distance "E" (see Fig., → ä 3) the level is calculated.
Alternatively, the level can be converted by means of linearization (32 points) into other variables (volume,
mass).

Measuring range The measuring range spans the entire probe. The upper blocking distance set in the delivery status can be

adapted as required (see recommendations in the "Blocking distance" chapter). The specified accuracy of the
probe is reduced in the upper and lower range of the probe (table, → ä 16), especially when using media with
a smaller dielectric constant (DC < 7).

Blocking distance The upper blocking distance (= UB) is the minimum distance from the reference point of the measurement

(lower edge of process connection) to the maximum level. At the lowest part of the probe an exact
measurement is not possible, see "Performance characteristics", → ä 16.

L00-FMP43xxx-17-00-00-en-001

Reference point of measurement, details → ä 26

The blocking distance is preset to 0.2 m when using rod probes. The blocking distance can be reduced when
the probe is installed flush with a wall or in a nozzle with a max. height of 50 mm.

When using a spray ball the blocking distance may not be smaller than 50 mm.

The AI block takes the manufacturer's input data,
selected by channel number, and makes it available to other
function blocks at its output.

30 ms standard

PID Block The PID block serves as proportional-integral-derivative

controller and is used almost universally to do closed-loop­control in the field including cascade and feedforward.

80 ms standard

Arithmetic Block This block is designed to permit simple use of popular

measurement math functions. The user does not have to
know how to write equations. The math algorithm is
selected by name, chosen by the user for the function to
be done.

50 ms standard

Input Selector
Block

The input selector block provides selection of up to four
inputs and generates an output based on the configured
action. This block normally receives its inputs from AI
blocks. The block performs maximum, minimum, middle,
average and ‘first good’ signal selection.

30 ms standard

Signal Characte­rizer Block

The signal characterizer block has two sections, each
with an output that is a non-linear function of the
respective input. The non-linear function is determined by a
single look-up table with 21 arbitrary x-y pairs.

40 ms standard

Integrator Block The Integrator Function Block integrates a variable as a

function of the time or accumulates the counts from a
Pulse Input block. The block may be used as a totalizer
that counts up until reset or as a batch totalizer that has a
setpoint, where the integrated or accumulated value is
compared to pre-trip and trip settings, generating discrete
signals when these settings are reached.

Overvoltage protector If the measuring device is used for the level measurement in flammable liquids which requires the use of an

overvoltage protection according to EN/IEC 60079-14 or EN/IEC 60060-1 (10 kA, pulse 8/20 μs) it has to
be ensured that

• the measuring device with integrated overvoltage protection with 600 V gas discharge tubes within the T12-

enclosure is used, refer to "Ordering information", → ä 42

or

• this protection is achieved by the use of other appropriate measures (external protection devices e.g.
