16 Endress + Hauser
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 soiling 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 → ä 61.

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.
