1) Feature 070 of the product structure
If the antenna doesn't extend below the nozzle, observe the following:
• The nozzle end must be smooth and free of burrs. If possible its edge should be rounded.
• An interference echo suppression must be performed.
• Please contact Endress+Hauser for applications with higher nozzles than those indicated in
the table.
• For mounting in heigh nozzles the device is available in a version with an antenna extension
of up to 1 000 mm (39.4 in)
5)
• The antenna extension may cause interference echoes in the near range. In this case it may
occur that the maximum measurable level is reduced.
Threaded connection
For devices with a threaded connection it may be necessary - depending on the antenna size -
to unmount the horn before fastening the device and to mount it again afterwards.
• Tighten with the hexagonal nut only.
• Tool : 55 mm hexagonal wrench
• Maximum permissible torque: 60 Nm (44 lbf ft)
Mesurement from the outside through plastic walls (FMR50/FMR51)
• Dielectric constant of the medium: ε
r
> 10
• If possible, use an antenna 100 mm (4 in).
• The distance from the lower edge of the antenna to the tank ceiling should be about
100 mm (4 in).
• If possible, avoid mounting locations where condensation or build-up might occur.
• In case of outdoor mounting, the space between antenna and vessel has to be protected from the
elements.
• Do not mount any potential reflectors (e.g. pipes) outside the tank in the signal beam.
