FMR62 - Aligning the antenna axis
Align the antenna so that it is perpendicular to the product surface.
Caution:
The maximum reach of the antenna can be reduced, or additional interference signals can
occur, if the antenna is not installed perpendicular to the product.
Radial alignment of the antenna
Based on the directional characteristic, radial alignment of the antenna is not necessary.

2) Feature 070 in the product structure
Note the following if the antenna does not project out of the nozzle:
• The end of the nozzle must be smooth and free from burrs. The edge of the nozzle should be
rounded if possible.
• Mapping must be performed.
• Please contact Endress+Hauser for applications with nozzles that are higher than indicated in
the table.
