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 > 4 m 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).
("Accessories", →ä75)

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 316L (1.4435)
• 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

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.
• 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°.

Installation in plastic containers
Please note that the "guided level radar" measurement 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 ≥200 mm must be mounted under the screw-in piece.

3.3.5 Installation with difficult-to-access process connections
Installation with remote electronics
• Wall and pipe bracket is contained in the scope of delivery and is already mounted.
• Mount the housing on the wall or pipe (vertically or horizontally, as required) as shown in the
diagram.
• The wall retainer can also be used for mounting in display panels.
Please observe the dimensions, →ä10 for the cutout.
L00-FMP43xxx-17-00-00-en-002
!Note!
The cable cannot be disassembled at these points (1).
The cable should never be bent or buckled.
The ambient temperature for the connecting line (2) between the probe and electronics can be
max. 105 °C. The version with remote electronics consists of the probe, a connecting cable and the
housing. If they are ordered as a set, they are assembled on delivery.
