LFP Inox

1.4 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 nozzle diameter in accordance with Diagram 1 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 the other tank components (e.g., supply pipes, other measuring devices) as well as
the sides or bottom of the container. These minimum distances are also specified in Diagram 1. The
LFP can also be used in a metal immersion tube or bypass. The installation conditions are shown
in Diagram 2. 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 has 360° rotation, allowing the cable outlet to be adjusted freely.
Installation in a container
Note: The LFP with remote amplifier has the same distances requirements.
