Installation
Special mounting
conditions
Mount the unit with-
in the inactive zone, if
possible (I; mounting
area M1). The active
zone (A) should be
completely
in
the
tank.
For an optimum func-
tion we recommend:
A part of the active
zone should be above
the upper edge of the
tank / above the over-
flow.
You can also fasten mounting elements in the two upper thirds of the
active zone (possible mounting area, M2). This reduces the active zone
to the area between mounting element and probe end. In this case the
mounting element should be above the upper edge of the tank /
above the overflow.
• If possible, mount the unit in the middle of the tank when it is
installed in small plastic tanks:
• For dirty media we recommend: Fasten the unit in a zone where
there is much movement of the medium (e.g. at the supply inlet).
• When installed in metal rising pipes (bypass) the sensor must be
mounted in the middle of the pipe. The inside diameter of the pipe
must be min. 120 mm.
• Metal objects within the tank
(e.g. metal pipes, components
integrated into the tank) must
observe a minimum distance
of 60 mm to the active zone of
the sensor. Otherwise, they are
detected as mounting element
(this reduces the active zone to
the area between metal object
and probe end).
• When installed in metal tanks
the distance between sensor
and tank wall / tank bottom
must be min. 20 mm.
