4.2 Mounting instructions
Figure 4.6
If the reflective properties of the medium are good, you can mount SITRANS LR150
on nozzles longer than the antenna. The nozzle end should be smooth and burr-free,
if possible also rounded.
You will find recommended values for nozzle heights in the following illustration or
the table. The values come from typical applications. Deviating from the proposed
dimensions, also longer nozzles are possible, however the local conditions must be
taken into account.

Note
When mounting on longer nozzles, we recommend carrying out a auto false echo
suppression (see chapter " Parameter adjustment").
Alignment - Liquids
In liquids, direct the device as perpendicular as possible to the medium surface to
achieve optimum measurement results.
