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 diagrams below must be observed.
The LFP must be installed so that after mounting there is sufficient distance to other tank
components (e.g. supply tubes, other measurement devices), the container wall or the
container bottom. These minimum distances are also specified in the diagrams.
The LFP can also be used in a metal immersion pipe or bypass. The installation
conditions are shown in the Figure on page 15.
Ensure 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.
