3.3 Installation
3.3.1 Mounting kit
For the mounting, you will require the following tool:
• The tool for flange mounting
• 4 mm (0.1") Allen wrench for turning the housing
3.3.2 Mounting probes
"Caution!
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.
3.3.3 General instructions
Normally use rod or coax probes for liquids. Rope probes are used in liquids for measuring ranges
> 4 m and with restricted ceiling clearance which does not allow the installation of rigid probes.
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!
Be sure to use unpainted metal bolts toensure
good electrical contact betweenprobe flange and
process flange.

Uncoil rope and lower
probe slowlyand
carefullyinto the silo
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)
("Accessories", →ä72).

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.
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
• When installing in plastic tanks, the nozzle must have at least DN50 (2"). The appropriate flange
must be used as the process connection.
• For nozzles up to 450 mm high, select the length of the centering rod appropriate for the nozzle
height when using rope probes.
• Use spring washers (1) (see Figure below).
!Note!
It is recommended to retighten the flange bolts periodically, depending on process temperature
and pressure. Recommended torque: 60 to 100 Nm.
• After mounting, the housing can be turned 350° in order to simplify access to the display and the
terminal compartment.
L00-FMP41Cxx-17-00-00-en-005
!Note!
The PTFE plating of the FMP41C is used for sealing to the process. Usually no other sealing is
necessary.
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", →ä72).
Supporting probes against warping
For WHG approval:
For probe lengths ≥3 m a support is required (see figure).

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.
L00-FMP4xxxx-17-00-00-yy-049

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
DN150 (6"), the measuring sensitivity of the
device increases such that liquids as of DC 1.4
can be measured.
• If a rod probe is used the probe length must be
100 mm longer than the lower disposal.
• 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 in plastic containers
Please note that the "guided level radar" measuring principle requires a metallic surface at the
process connection! When installing rod or robe probes in plastic silos, whose silo cover is also made
of plastic or silos with wood cover, the probes must either be mounted in a ≥DN50 (2") metallic
flange, or a metal sheet with diameter of ≥200 mm must be mounted under the screw-in piece.
L00-FMP4xxxx-17-00-00-en-018
Installation at an angle
• For mechanical reasons, the probe should be
installed as vertically as possible.
• With inclined installations the probe length
has to be adjusted in dependence to the
installation angle.
– up to 1 m = 30°
– up to 2 m = 10°
– up to 4 m = 5°.
