Installation
Position for installation on a vessel
Figure 10.2 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 inch)
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 foot) is configured as standard.
However, this can be overwritten manually (0 m (0 foot) is also permitted).
Automatic calculation:
Blocking distance = Empty calibration – Full calibration – 0.2 m (0.656 foot).
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 foot), the Blocking distance
of 0.1 m (0.33 foot) will continue to be used.
