2.4.1.3 Obstructions
Almost any object that falls within the beam pattern will cause reflections that may be misinterpreted as a false liquid level.
Although PULSAR Model R96 has a powerful Echo
Rejection routine, all possible precautions should be taken to minimize false target reflections with proper installation and orientation. Refer to section 2.4.2.3 for additional information.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “ringing” that will adversely affect measurement. The antenna should always be mounted so the active section of the antenna is a minimum of 0.5" (12mm) outside the nozzle. Antenna extensions are offered to allow the PULSAR Model R96 transmitter to work reliably in nozzles with “L” dimensions of 1" (25 mm),
4" (100mm), 8" (200mm) or 12" (300mm). Standard antennas (no extension) are shown below for reference. See
Section 3.7.6 for dimensional drawings of all antenna designs including nozzle extensions.
