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.
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
