3.4 Installation
3.4.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
• For the mounting of threaded connection: 60 mm Open-end spanner for 1½", 50 mm Open-end
spanner for ¾".
• 4 mm Allen wrench for turning the housing.
3.4.2 Shortening probes
Rod probe
The shortening is necessary if the distance to the container floor or outlet cone is less than 50 mm.
The rods of a rod probe are shortened by sawing or separating at the bottom end.
Rope probes
Coax probes
The shortening is necessary if the distance to the container floor or outlet cone is less than 10 mm.
Coax probes can be shortened max. 80 mm from the end. They have centering units inside which
fix the rod centrally in the pipe. The centerings are held with borders on the rod. Shortening is
possible up to approx. 10 mm below the centering.
The shortening is necessary if the distance to the
container floor or outlet cone is less than 150
mm.
• Remove ballast weight:
– The weight is fixed to the probe rope with 3
Allen setscrews (M4, Allen key AF3). The
screws are secured with Loctite. This may
first have to be made plastic with a hot air
apparatus.
• Remove released rope from the weight
• Measure off new rope length
• Wrap adhesive tape around the rope at the
point to be shortened to prevent it from
fanning out.
• Saw off the rope at a right angle or cut it off
with a bolt cutter.
• Insert the rope completely into the weight,
– thin rope (4 mm) 60 mm deep,
– thick rope(6 mm) 80 mm deep
The weight is then refixed to the rope:
• Reapply screw locking fluid (we recommend
Loctite type 243) to the setscrews and screw
into place.
• When doing so, observe the following
torques:
– For 6 mm rope: 15 Nm
– For 4 mm rope: 5 Nm

3.4.3 Mounting probes in an empty silo
"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.
Levelflex can be screwed into a threaded socket or flange. Proceed as follows:
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.
– For flange mounting: if a seal is used, be
sure to use unpainted metal bolts toensure
good electrical contact betweenprobe flange
and process flange.

3.4.4 Mounting rope probes in a partially full silo
It is not always possible to empty a silo which is already in operation. Because the probe can be
turned in the threaded boss, it can also be mounted when the silo is only partially filled. In order to
avoid problems when Levelflex is mounted into a partially full silo, the following measures should
be taken:
• Mount when the silo is as empty as if possible. A minimum of 2/3 of the silo must be empty.
After mounting, map must be made should the installation conditions require it.
"Caution!
If there is a risk of electrostatic discharge from the product, the housing must be earthed before the
probe is lowered into the silo.
!Note!
Before full accuracy is obtained the probe rope must hang fully extended.
Screw down
• If appropriate, screw the Levelflex into the
threaded flange.
• Turn with the hexagonal nut only:
torque 10...20 Nm
• For flange mounting: if a seal is used, be sure
to use unpainted metal bolts to ensure good
electrical contact between probe flange and
process flange.
• When installing in metal silos, take care to
ensure good metallic contact between the
process connection and silo.

• Avoid tangles.
• Avoid any backlash, since this might damage
the silo fittings.
• If possible, make a visual check to see that the
rope has not tangled or is lying such that it can
knot when the level falls. This is
particularly important if a flange was not used.
Re-insert the probe if necessary.
• Screw the flange to the counterflange on the
nozzle.

3.4.5 General instructions
Normally use rod probes. Rope probes are used in liquids for measuring ranges > 4m and with
restricted ceiling clearance which does not allow the installation of rigid probes.
Coax probes are not influenced by the installation conditions. They may also be operated
• in the filling curtain
• in arbitrary proximity to internal fittings
• at viscositys up to 500 cSt.
!Note!
Seal for devices with G 1½" thread
The thread and the type of seal comply to DIN 3852 part 1, screwed end type A. Gaskets according
to DIN 7603 with a dimesnion of 48x55mm can be used for it. Please use a gasket according to this
standard in the form A, C or D and of a material that is resistant to your application.
Mounting location
• Do not mount rod or rope probes in the filling
curtain (2).
• 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: 100 mm
– Coax probe: 10 mm
• When installing outdoors, it is recommended
that you use a protective cover (1) see
Accessories on →ä65.

Minimum distance B of rod and rope probes 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 no bridges to the wall created by soiling or highly viscous media.
Welding the probe into the vessel
"Caution!
Before welding the probe into the vessel, it must be grounded by a low-resistive connection. If this
is not possible, the electronics as well as the HF module must be disconnected. Otherwise the
electronics may be damaged.
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.

Probe length
The measuring range is directly dependent on the probe length.
It is better to order probes too long than too short since it is possible to shorten the probe if
necessary.
