Polarisation direction
The emitting unit emits electromagnetic waves. The polarisation
plane is the direction of the electrical wave component. Its position is
marked on the instrument hexagon by polarisation markings.
For a reliable function, the emitting and receiving units must be
installed in the same polarisation direction.
If multiple instrument pairs are installed in one vessel, the instrument
pairs can be coded, so to speak, by mounting them in different polari

sation positions so that they do not influence one another.
