NOTICE
Damage to the flange
If mating flange faces are not flat and free of distortion, then bolting the flanged process
connection may produce a bending load on the device's flange. Cracking or other damage
may occur.
Use only 'full-face' flat gaskets surrounding the bolt holes. Ensure mating flange faces are
flat and free of distortion.

Nozzle location

Avoid central locations on tall, narrow vessels
Beam angle
● Beam angle is the width of the cone where the energy density is half of the peak energy
density.
● The peak energy density is directly in front of and in line with the antenna.
● There is a signal transmitted outside the beam angle, therefore false targets may be
detected.
