Avoid central locations on vessels

For vessels with conical or parabolic tops, avoid mounting the device at the center. The

concavity of the top can focus echoes into the center, giving false readings.

Nozzle location

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 rod antenna.

● There is a signal transmitted outside the beam angle, therefore false targets may be

detected.

Process temperature: –40 to 80 °C (–40 to 176 °F)

Locking collar over threaded connection; secured by three 2 mm Allen set-screws.

When the locking collar is secured, it prevents the enclosure rotating on the threaded connec-

tion.
