Improper installation in a nozzle creates “ringing” which will
adversely affect measurement. The antenna should always be
mounted so the active section of the antenna is a minimum of
0.5" (12 mm) below the nozzle (be sure to include any nozzle
dimension
inside
the vessel). Refer to Figure 9. Antenna exten-
sions are offered to allow the PULSAR transmitter to work reliably
in nozzles with “L” dimensions of 1" (25 mm), 4" (100 mm),
8" (200 mm) or 12" (300 mm). Standard antennas are shown
below for reference.
