Micropilot FMR56, FMR57
Endress+Hauser V. 1, Rev. 6, 19-10-2012 41
Parabolic antenna (FMR57)
Alignment
Ideally, the parabolic antenna should be installed vertically. To avoid interference reflections or for optimum
alignment within the vessel, the Micropilot with optional alignment device can be swiveled by 15° in all
directions (® ä 44).
Nozzle mounting
• Ideally, the parabolic antenna should protrude from the nozzle (1). Particularly when using the alignment
device, please ensure that the parabolic reflector is protruding from the nozzle/roof so as not to inhibit
alignment.
• For applications with higher nozzle it may be necessary to install the parabolic antenna completely in the
nozzle (2).
The maximum height of the nozzle (H
max
) to the parabolic mirror should not exceed 500 mm (19.7 in).
Interfering edges within the nozzle should be avoided.
