Notes on special installation
situations
Endress+Hauser
When installing in stirring tanks, observe lateral load-bearing capacity of rod probes (→ Page 4). Possibly check
whether a non-contact process, Ultrasonic or Level-Radar would not be better suited, above all if the stirrer
generates large mechanical loads on the probe.
Installation in horizontal cylindrical and
standing tanks
• Use a rod probe for measuring ranges up to 13 ft
(4 m). For anything over this or if there is too much
free cover space use, a 0.16" (4 mm) cable probe.
• Any distance from wall, as long as occasional
contact is prevented.
• When using metal tanks, it is preferable to mount
probes (1) eccentrically.
Installation in stilling well or bypass
• Rod and cable probes can also be installed in pipes
(stilling well, bypass).
• When installing in metal pipes up to 6" (DN150),
the measuring sensitivity of the device increases
such that liquids with a DK 1.4 can be measured.
• Welded joints that protrude up to approx. 0.2"
(5 mm) inwards do not influence measurement.
Caution!
For FMP45: In vacuum applications and in applications where extreme condensate formation may occur, there is
the danger that the vessel may be completely flooded. For media groups with high DC values, this may result in
a measuring value lower than the actual level. Please contact your local Endress+Hauser representative for reme-
dial actions.
Installation at an angle
• For mechanical reasons, the probe should be
installed as vertically as possible.
• Installation with a deviation up to approx. 5° from
the vertical axis is permitted for probes up to
approx. 3 ft (1 m) in length.
