Before You Begin
2.3.1 Site Preparation
Each PULSAR Model R86 Radar transmitter/antenna is
built to match the physical specifications of the required
installation. Ensure that the antenna process connection is
correct for the threaded or flanged mounting on the vessel
where the transmitter will be placed. See Mounting,
Section 2.4.
Ensure that all local, state, and federal regulations and
guidelines are observed. See Wiring, Section 2.5.
Ensure that the wiring between the power supply and
PULSAR Model R86 Radar transmitter is complete and
correct for the type of installation. See Specifications,
Section 3.7.

2.3.3 Operational Considerations
Radar applications are characterized by three basic condi-
tions;
• Dielectric (process medium)
• Distance (measuring range)
• Disturbances (turbulence, foam, false targets, multiple
reflections and rate of change).
The PULSAR Model R86 Radar transmitter is offered with
a horn antenna configuration—Horn (1½", 2", 3", 4").
Ideally, if the installation allows, the 4" (DN100) horn
antenna should be used to ensure the best possible perform-
ance in all operational conditions.
