Operating conditions: Installation

Probe selection (see overview on → Page 4)
• In normal cases, use rod probes. Cable probes are used for measuring ranges > 13 ft (4 m) or when the
overhead clearance does not allow the installation of rigid probes.
Mounting location
• Do not mount rod or cable probes in the filling
curtain (2)
• Mount rod and cable 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 4"
(100 mm) between the probe and the build-up.
• Mount rod and cable probes as far away as possible
from installed fittings. "Mapping " must be carried
out during commissioning in the event of distances
< 12" (300 mm).
• Minimum distance of probe end to the container
floor (C):
– Cable probe: 6" (150 mm)
– Rod probe: 2" (50 mm)
– Coax probe (FMP45 only): 0.4" (10 mm)
• When installing outdoors, it is recommended that
you use a protective cover (1) see "Accessories" on
→ Page 45.
Note!
Seal for devices with G 1½" thread
The thread and the type of seal comply to DIN 3852 part 1, threaded end type A. Gaskets accordingto DIN
7603 with a dimesnion of 1.89" x 2.17" (48 x 55 mm) 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.
Tank internals
• Select the mounting location such that the distance
to internals (5) (e.g. limit switch, struts) > is 12"
(300 mm) over the entire length of the probe, also
during operation.
• The probe must not touch any internal objects
within the measuring range during operation.
Optimization options
• Interference echo suppression: measurement can
be optimized by electronically tuning out
interference echoes.
