• Recommended distance A from wall to
outer edge of nozzle: ~ 1/6 of vessel
diameter.
Nevertheless the device should not be
installed closer than 20 cm (7.87 in) to
the vessel wall.
If the wall of the vessel is not smooth
(corrugated metal, welding seams,
irregularities etc.) the distance from the
wall should be kept as large as possible.
If necessary, use an alignment device to
prevent interference reflections from
the wall →  32.

cause signal loss.

• It is recommended to us a weather
protection cover (1) in order to protect
the device from direct sun or rain.
