!Note!
This operating manual explains the installation and initial start-up for the level transmitter
measuring device. All functions that are required for a typical measuring task are taken into account
here.
In addition, the Levelflex M provides many other functions that are not included in this operating
manual, such as optimising the measuring point and converting the measured values.
An overview of all device functions can be found on Page 96.
An extensive description of all device functions can be found in BA245F – "Description of the

1 Safety instructions
1.1 Designated use
The Levelflex M FMP41C is a compact level transmitter for the continuous measurement of solids
and liquids, measuring prinziple: Guided Level Radar / TDR: Time Domain Reflectometry.
1.2 Installation, commissioning and operation
The Levelflex M has been designed to operate safely in accordance with current technical, safety
and EU standards. If installed incorrectly or used for applications for which it is not intended,
however, it is possible that application-related dangers may arise, e.g. product overflow due to
incorrect installation or calibration. For this reason, the instrument must be installed, connected,
operated and maintained according to the instructions in this manual: personnel must be authorised
and suitably qualified. The manual must have been read and understood, and the instructions
followed. Modifications and repairs to the device are permissible only when they are expressly
approved in the manual.
1.3 Operational safety
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this supplementary documentation is mandatory.
• Ensure that all personnel are suitably qualified.
• Observe the specifications in the certificate as well as national and local regulations.

If the device has this symbol embossed on its name plate it can be installed in an explosion hazardous
area
-
Explosion hazardous area
Symbol used in drawings to indicate explosion hazardous areas. Devices located in and wiring
entering areas with the designation “explosion hazardous areas” must conform with the stated type
of protection.
.
Safe area (non-explosion hazardous area)
Symbol used in drawings to indicate, if necessary, non-explosion hazardous areas. Devices located in
safe areas still require a certificate if their outputs run into explosion hazardous areas
Electrical symbols

If there is a risk of electrostatic discharge from the product, then both processconnection and rope
must be earthed before the probe is lowered into the silo.
Insert probe
• Uncoil rope and lower it slowly and carefully
into the silo.
• Do not kink the rope
• Avoid any backlash, since this mightdamage
the probe or the silo fittings.
•
!
Note!
– Flanges: bolt the flange in positionbefore
inserting the cable into the silo.
– Be sure to use unpainted metal bolts
toensure good electrical contact
betweenprobe flange and process flange.

3.3.3 General instructions
Normally use rod or coax probes for liquids. Rope probes are used in liquids for measuring ranges >
4m and with restricted ceiling clearance which does not allow the installation of rigid probes.
Minimum distance B of the probe to the container wall:
The wall clearance can be chosen as desired as long as the probe does not touch the tank wall.
!Note!
• There should be no metallic parts or persons moving when installation is made in plastic tanks,
also on the outside of the tank at a distance of 300 mm to the probe.
• There should no bridges to the wall created by build up or highly viscous media.
Mounting location
• Do not mount rod or rope probes in the filling
curtain (3).
• Mount rod and rope probes away from the
wall (B) at such a distance that, in the event of
build-up on the wall, there is still a minimum
distance of 100 mm between the probe and
the build-up.
• Mount rod and rope probes as far away as
possible from installed fittings. "Mapping "
must be carried out during commissioning in
the event of distances < 300 mm.
• Minimum distance of probe end to the
container floor (C):
– Rope probe: 150 mm
– Rod probe: 50 mm
• When installing outdoors, it is recommended
that you use a protective cover (1) see
Accessories on Page 74.

Other installations
• Select the mounting location such that the
distance to internals (5) (e.g. limit switch,
struts) > is 300 mm over the entire length of
the probe, also during operation.
• Probe must within the measuring span not
touch any internals during operation.
Optimization options
• Interference echo suppression: Measurement
can be optimised by electronically tuning out
interference echoes.

Type of probe mounting
The coupling nut must be tightened using a torque of 5 up to a maximum of 10 Nm when installing
the FMP41C in the universal adapter ("Welding boss for adapter 43 mm" see Page 74).
Supporting probes against warping
For WHG or Ex approval:
For probe lengths ≥3 m a support is required (see figure).
L00-FMP4xxxx-17-00-00-en-065
• When installing in plastic tanks, the nozzle
must have at least DN50/2". The appropriate
flange must be used as the process connec-
tion.
• For nozzles up to 450 mm high, select the
length of the centering rod appropriate for the
nozzle height when using rope probes.
• If the FMP41C is mounted using a flange,
place spring elements (e.g. cup springs) under
the flange screws to compensate any deforma-
tion of the PTFE or retighten the flange screws
from time to time.

3.3.4 Special instructions
When installing in stirring tanks, observe lateral load of probes. Possibly check whether a non-
contact process, ultrasound or radar would not be better suited, above all if the stirrer generates
large mechanical loads on the probe.
Installation in horizontal cylindrical and
standing tanks
• Use a rod probe for measuring ranges up to 4
m. For anything over this or if there is too free
cover space use a rope probe.
• Any distance from wall, as long as occasional
contact is prevented.

Installation in stilling well or bypass
• Rod and rope probes can also be installed in
pipes (stilling well, bypass).
• When installing in metal pipes up to DN 150/
6", the measuring sensitivity of the device
increases such that liquids as of DK 1.4 can be
measured.
• Welded joints that protrude up to approx. 5
mm/0.2" inwards do not influence
measurement.

3.3.5 Notes on special installation situations
Installation at an angle
• For mechanical reasons, the probe should be
installed as vertically as possible.
• Installation with a deviation up to approx. 5°
from the vertical axis is permitted for probes
up to approx. 1 m in length.
L00-FMP4xxxx-17-00-00-de-048
0...5°
max. 1 m
Fixing rope probe
• The end of the probe needs to be secured if
the probe would otherwise touch the silo
wall, the cone or another part, or the probe
comes closer than 0.5 m to a concrete wall.
This is what the internal thread in the probe
weight is intended for:
– for 4 mm rope: M 14
– for 6 mm rope: M 20
• Preferably use the 6 mm rope probe due to the
higher tensile strength when fixing a rope
probe.
• The fixing must be either reliably grounded or
reliably insulated (see "Accessories" on
Page 77)! If it is not possible to mount the
probe weight with a safe earthed connection,
it can be secured using an isolated eyelet,
which is available as an accessory (see
Page 77).
• In order to prevent an extremely high tensile
load and the risk of rope crack, the rope has to
be slack. Make the rope longer than the
required measuring range such that there is a
sag in the middle of the rope that is ≥1cm/m
(1"/100") of the rope length.

3.3.6 Installation for difficult to access process connections
Installation with remote electronic
• Follow installation instructions on Page 16 ff.
• Mount housing on a wall or pipe as shown in the diagram.
L00-FMP4xxxx-17-00-00-en-015
!Note!
The protective hose cannot be disassembled at these points (1).
The ambient temperature for the connecting line (2) between the probe and the electronics must
not be greater than 105°C. The version with remote electronics consists of the probe, a connecting
cable and the housing. If they are ordered as a complete unit they will be delivered assembled and
cannot be separated.
