The bottom line
False-echoes are one of the largest problems for process radar transmitters. Circular polarization, which is a unique feature for the 5400, reduces the problem with double bounces since it inherently rejects an even number of bounces. Not in the software but in the hardware itself due to the “intelligent” microwaves.

The circular polarization is one of the key features that make the Rosemount 5400 Series deliver like no 2-wire radar in history. The results are higher reliability and less maintenance and configuration, resulting in reduced process downtime and lower installation and operating costs.
