During installation, the polar marker of the radar level gauge should be at 90° to the vent hole on the waveguide; only in this orientation can stable and reliable measurements be ensured. The diameter of the vent hole should be no more than 5 mm (as specified for VEGA radars), while domestic specifications indicate a range of 5–10 mm.
