Mounting without Guide System
NMS5 is mounted on a nozzle of the tank roof without any guide system (Refer to Figure. 14: Application for
Each Tank). The mounting preparations require the observance of some recommendations for setting the noz-
zle and the minimum measuring level.

Mounting with Stilling Well
Stilling Well Diameter
The stiling well diameter that is required to protect the measuring wire without disturbing its operation varies
depending on the tank height. The stiling well could either be constant diameter, or thinner at its upper part
and thicker at its lower part. The figure 16 shows two examples of the latter case, namely an asymmetric pipe
and a concentric pipe.
