!Note!
These Operating Instructions explain how to install and commission the level transmitter. All the
functions that are required for a typical measuring task are taken into account here.
In addition, the Levelflex M has many other functions that are not included in these Operating
Instructions, such as functions for optimizing the measuring point and converting the measured
value.
An overview of all the instrument functions can be found on →ä98.
An extensive description of all the instrument functions can be found in BA245F –

Safety instructions Levelflex M FMP43 with FOUNDATION Fieldbus
6Endress+Hauser
1 Safety instructions
1.1 Designated use
The Levelflex M FMP43 is a compact level transmitter for continuous measurement in liquids, using
the guided level radar/TDR: time domain reflectometry measuring principle.
1.2 Installation, commissioning and operation
The Level M is designed to meet state-of-the-art safety requirements and conforms to applicable
standards and EC regulations. If installed incorrectly or used for applications for which it is not
intended, however, the instrument can present a source of application-related danger, e.g. product
overflow due to incorrect installation or configuration. For this reason, installation, connection to
the electricity supply, commissioning, operation and maintenance of the measuring system must
only be carried out by trained, qualified specialists authorized to perform such work by the facility's
owner-operator. The specialists must have read and understood these Operating Instructions and
must follow the instructions they contain. Modifications and repairs to the instrument are
permissible only when they are expressly approved in the Operating Instructions.
1.3 Operational safety and process safety
Alternative monitoring measures must be taken to ensure operational safety and process safety
during configuration, testing and maintenance work on the device.
Hazardous area
Applicable national standards must be observed when using the measuring system in hazardous
areas. The instrument is accompanied by separate “Ex documentation”, which is an integral part of
this documentation. The installation regulations, connection values and safety instructions listed in
this document must be observed.
• Ensure that all personnel are suitably qualified.
• Measuring point requirements with regard to measurement and safety must be observed.

1.4 Notes on safety conventions and icons
In order to highlight safety-relevant or alternative operating procedures in the manual, the following
conventions have been used, each indicated by a corresponding symbol in the margin.
Safety instructions
#Warning!
Indicates
an action or procedure which, if not performed correctly, can result in serious personal
injury, a safety hazard or the destruction of the instrument.
"Caution!
Indicates
an action or procedure which, if not performed correctly, can result in personal injury or the
incorrect operation of the instrument.
!Note!
Indicates an action or procedure which, if not performed correctly, can have
an indirect effect on operation or trigger an unexpected response on the part of the instrument.
Explosion protection
0Explosion protected, type-examined equipment
If the instrument has this symbol embossed on its nameplate, it can be used in a hazardous area or a
non-hazardous area, according to the approval
-Explosion hazardous area
This symbol is used in the drawings of these Operating Instructions to indicate hazardous areas.
Instruments in hazardous areas, or cables for such instruments, must have appropriate explosion
protection.
.Safe area (non-hazardous area)
This symbol is used in the drawings of these Operating Instructions to indicate non-hazardous areas.
Instruments in the non-hazardous area also have to be certified if connecting cables lead into the
hazardous area.
Electrical symbols
%Direct current
A terminal to which DC voltage is applied or through which direct current flows.
&Alternating current
A terminal to which alternating voltage (sine-wave) is applied or through which alternating current
flows.
)Ground connection
A grounded terminal which, as far as the operator is concerned, is grounded by means of a grounding
system.
*Protective ground connection
A terminal which must be connected to ground prior to making any other connection to the equipment.
+Equipotential connection
A connection that has to be connected to the plant grounding system:
This may be a potential equalization line or a star grounding system depending on national or company
codes of practice.
Temperature resistance of the connecting cables
Indicates that the connecting cables have to withstand a temperature of 85 C at least.
Safety instruction
For safety instructions refer to the manual for the appropriate instrument version.

3.3 Installation instructions
3.3.1 Mounting tools
A 4 mm Allen key is needed to turn the housing.
3.3.2 General instructions
Normally use rod probes. Rope probes are used for measuring ranges > 4m and with restricted
ceiling clearance which does not allow the installation of rigid probes.
!Note!
You must ensure that the probe does not come into contact with the container wall, container
bottom and tank internals.
Mounting location
• Do not mount the probe in the filling curtain
(2).
• Mount the probe at such a distance away from
the wall (B) that, in the event of buildup on
the wall, there is still a minimum distance of
100 mm between the probe and the buildup.
• Mount the probe as far away as possible from
internals.
• The minimum distance from the probe end to
the tank floor is 10 mm.
• If installing outdoors, it is recommended that
you use a weather protection cover (1). See
"Accessories" on →ä78.

C
Tank internals
• If the distance to the internals is < 300 mm,
"mapping" must be carried out, and the
measurement capability may be restricted.
• During operation, the probe must not touch
any internals within the measuring range.
Optimization options
• Interference echo suppression: measurement
can be optimized by electronically suppressing
interference echoes.

3.3.3 Special instructions
When installing in tanks with agitator, observe the lateral loading capacity of rod probes:
• 10 Nm with 1.4435 / SS316L
• 16 Nm with Hasteloy C22 (on request).
The formula for calculating the bending torque M impacting on the probe:
with
cw: Friction factor
ρ [kg/m3]: Density of the medium
v [m/s]: Velocity of the medium perpendicular to the probe rod
d [m]: Diameter of the probe rod (8 mm)
L [m]: Level
LN[m]: Probe length
L00-FMP43xxx-16-00-00-de-004
Calculation example

current (high Reynolds number ))

3.3.4 Notes on special installation situations
The probe must be mounted opposite the
agitator.
If possible, check whether a non-contact
process, ultrasonic or level-radar would be
better suited, particularly if the agitator
generates large mechanical loads on the probe.
L00-FMP43xxx-17-00-00-xx-005
Installation at an angle
• For mechanical reasons, the probe should be
installed as vertically as possible.
• The maximum mounting angle is
– up to 1 m = 30°
– up to 2 m = 10°
– up to 4 m = 5°.
