1.4 Installation conditions
The
NGR
is mounted vertically from above into the container or bypass, using its process
connection. The
NGR
level sensor has a G ¾ or ¾" NPT threaded connection. Observe a minimum
connection diameter in accordance with the following Diagrams 1 and 3. The
NGR
must be
installed so that after
mounting there is sufficient distance to other tank components (e.g., supply
tubes, other measure
ment devices), the container wall, or the container bottom. Minimum
distances are also described in Diagrams 1 and 3. The
NGR
can also be used in a metal
immersion pipe or bypass. The installation conditions are shown in Diagram 2. Ensure that there is
a good metallic
connection between the NGR 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.
Installation in a container
Note:
The distances are the same for the sensor with remote amplifier.
