VIII. Installation
a. Direct mounting sensor: simply thread sensor into metal or plastic nozzle.
b. Radar unit MUST be installed into a fitting with the antenna pointing
downward. (See Figure 3.)
c. For very low dielectric constant materials (≈ 2), the radar sensor needs at
least 2' from the antenna tip to detect the material. Any buildup on the rod
antennas does not deteriorate the performance of the radar sensors.
