The maximum length of the nozzle L depends on the nozzle diameter D.
Please note the limits for the diameter and length of the nozzle.
Mounting outside the nozzle
• D: min. 40 mm (1.5 in)
• L: max. D × 1.5
Mounting inside the nozzle
• D: min. 80 mm (3 in)
• L: max. 140 mm (5.5 in) + D × 1.5

 5 Installation position on a vessel
• If possible install the sensor so that its lower edge projects into the vessel.
• Recommended distance A wall - nozzle outer edge: ~ ¹⁄₆ of the vessel diameter D. Under
no circumstances should the device be mounted closer than 15 cm (5.91 in) to the vessel
wall.
• Do not install the sensor in the middle of the vessel.
• Avoid measurements through the filling curtain.
• Avoid equipment such as limit switches, temperature sensors, baffles, heating coils etc.
• No signals are evaluated within the Blocking distance (BD). It can therefore be used to
suppress interference signals (e.g. the effects of condensate) in the vicinity of the
antenna.
An automatic Blocking distance of at least 0.1 m (0.33 ft) is configured as standard.
However, this can be overwritten manually (0 m (0 ft) is also permitted).
Automatic calculation:
Blocking distance = Empty calibration - Full calibration - 0.2 m (0.656 ft).
Each time a new entry is made in the Empty calibration parameter or Full calibration
parameter, the Blocking distance parameter is recalculated automatically using this
formula.
If the result of the calculation is a value < 0.1 m (0.33 ft), the Blocking distance of
0.1 m (0.33 ft) will continue to be used.
5.1.4 Device alignment for installation on a vessel
• Align the antenna vertically to the product surface.
• Align the eyelet with lug towards the vessel wall as well as possible.
