The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation plane is the direction of the electrical wave
component. By turning the instrument in the connection flange or
mounting boss, the polarisation can be used to reduce the effects of
false echoes.
The position of the polarisation plane is marked on the process fitting
of the instrument.
