    Hexagon screws on the antenna socket Antenna Mounting instructions Polarisation The emitted radar impulses of the radar sensor are electromagnetic waves. The polarisation is the direction of the electrical wave compo- nent. 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 is marked on the process fitting of the instrument. VEGAPULS 62 • 4 … 20 mA/HART - two-wire...
