How to attach antenna extensions (long antennas only)
How to attach antenna extensions (long antennas only)How to attach antenna extensions (long antennas only)
How to attach antenna extensions (long antennas only)
•Attach the antenna extensions 1to the flange.
•Attach the antenna 2.
•Make sure the antenna extensions are fully engaged.
•Use a 3 mm Allen wrench to tighten the locking screws 3.
•If you attach more or less extensions than were initially ordered, change
the antenna extension value in the OPTIWAVE program mode. Use the
display screen or PACTware™.
iAntenna extension = antenna extension length x number of extensions
•If you attach more extensions than were initially ordered, change the
blocking distance value in the user interface.
iMinimum blocking distance = antenna length + (antenna extension
length x number of extensions) + 0.1 m / 4"

Installation recommendations
We recommend that you prepare the installation when the tank is empty.
1Do not tilt the instrument more than 2°
2If there are too many objects in the radar beam, do an empty spectrum scan (refer to the hand-
book) or install a bypass chamber or stilling well
32.5 mm / 0.1" max. for liquids with high dielectric constants
4Curved and conical tank bottoms: Refer to the handbook for fine adjustment of the instrument
5Radar beam of DN40 antenna: 180 mm/m or 7 1/8"/3.3 ft (20°)
6Radar beam of DN50 antenna: 130 mm/m or 5 1/8"/3.3 ft (15°)
7Radar beam of DN80 antenna: 90 mm/m or 3 1/2"/3.3 ft (10°)
