3.3.5 Notes on special installation situations
Installation at an angle
• For mechanical reasons, the probe should be
installed as vertically as possible.
• With inclined installations the probe length
has to be adjusted in dependence to the
installation angle.
– up to 1 m = 30°
– up to 2 m = 10°
– up to 4 m = 5°.
Installation in plastic containers
Please note that the "guided lever radar" measurement principle requires a metallic surface at the
process connection!
When installing rod or robe probes in plastic silos, whose silo cover is also made of plastic or silos
with wood cover, the probes must either be mounted in a ≤ DN 50 / 2" metallic flange, or a metal
sheet with diameter of ≥ 200 mm must be mounted under the screw-in piece.
