Mounting
5.1
Installation conditions
The LFP is mounted vertically from above into the container or bypass, using its
process connection. The LFP level sensor has a G ¾ or ¾" NPT threaded connection.
A minimum connecting piece diameter in accordance with the figures below must be
observed.
The LFP is to be installed in such a way that, after it has been mounted, there is a
sufficient distance between it and other tank components (e.g., supply pipes, other
measuring devices) as well as the sides and bottom of the container. These minimum
distances are also specified in the figures.
The LFP can also be used in a metal immersion pipe or bypass. The installation condi-
tions are shown in the figure on page 15.
Make sure that there is a good metallic connection between the LFP measuring device
and the tank/bypass. When operating the sensor, ensure that the ambient temperature
is not above or below the limits.
Insulating the sensor housing is not permitted for tanks with hot media.
When positioning the device, ensure that the sensor is not directly exposed to the filling
flow.
The sensor housing can be rotated 360°, allowing for the cable outlet to be positioned
freely.
